It should be understood that although the steps in the flowcharts of the embodiments of this application are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows.

[0023] While existing experimental research methods for fans in water heaters can provide relatively intuitive and accurate data, they are technically challenging because they directly use flue gas as the working medium. They also require complex and precise experimental equipment and a large amount of experimental materials, resulting in low product development efficiency.
[0024] This application provides a fan simulation method. It involves determining the interaction interface of a target fan and the corresponding interaction parameters; constructing a control body model of the target fan based on the interaction parameters, wherein the control body model describes the correspondence between the interaction parameters input to the target fan and the target fan output; and building a fan twin model corresponding to the target fan based on the interaction interface and the control body model. Thus, by describing the correspondence between the interaction parameters involved in the interaction between the target fan and the external environment and the target fan output, this application constructs a fan twin model for building a fan twin model. This allows for the accurate simulation of fluid changes before and after passing through the target fan, effectively improving the product development efficiency of fans in water heaters.
[0025] Based on this, the embodiments of this application provide a wind turbine simulation method, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the wind turbine simulation method of this application.
[0026] In this embodiment, the wind turbine simulation method includes steps S10 to S30: Step S10: Determine the interaction interface of the target wind turbine and the corresponding interaction parameters of the interaction interface; It should be noted that the interaction interface is the data interface corresponding to the interaction between the target fan and the external environment, used for the target fan to transmit interaction parameters with the outside world. The interaction parameters may include fluid parameters such as fluid temperature, pressure, and flow rate, as well as mechanical operating parameters such as speed and power indicating the operation of the target fan.
[0027] In this embodiment, the interaction interface of the target fan and the corresponding interaction parameters can be determined according to the simulation scenario requirements of the target fan. For example, if only a scenario of simulating the target fan at a fixed fan speed or power is required, then the fluid interface for transmitting fluid parameters can be determined as the interaction interface, and the fluid parameters can be used as the interaction parameters. If a scenario of simulating multiple fan speeds or power is required, then the changes in fluid parameters under different mechanical operating parameters need to be considered. Therefore, the fluid interface for transmitting fluid parameters and the mechanical interface for transmitting mechanical operating parameters can be determined as the interaction interface, and the fluid parameters and the mechanical operating parameters can be used as the interaction parameters. It is understood that the external environment can be other components (such as ventilation ducts, controllers, etc.) in the gas water heater that are physically or electrically connected to the target fan.
[0028] In one feasible implementation, step S10 may include steps S11-S12: Step S11: Obtain interaction scenario information between the target wind turbine and the outside world; Step S12: Based on the interaction scenario information, select the data interface used to transmit the fluid parameters corresponding to the interaction between the target fan and the external fluid as the fluid interface, and the data interface used to transmit the mechanical operating parameters corresponding to the operation of the target fan as the mechanical interface, and use the fluid interface and the mechanical interface as the interaction interface.
[0029] It should be noted that the interaction scenario information may include a description of relevant parameters for the interaction between the target fan and the outside world, such as the temperature, pressure, and flow rate of the fluid (i.e., air), and the speed and power of the target fan as indicated by the controller.
[0030] It should also be noted that the fluid interface is a data interface used to transmit fluid parameters, such as temperature, pressure, and flow rate, for the interaction between the target fan and the external fluid. The mechanical interface is a data interface used to transmit the mechanical operating parameters of the target fan, such as the fan's speed and power.
[0031] This embodiment can filter the interaction interfaces required for modeling from the relevant parameters involved in the real-world interaction between the target wind turbine and the external environment. This embodiment can use the data interface for transmitting fluid parameters corresponding to the interaction between the target wind turbine and the external fluid as the fluid interface, and the data interface for transmitting mechanical operating parameters corresponding to the operation of the target wind turbine as the mechanical interface. It is understood that the parameters involved in the fluid interface and the mechanical interface can be adjusted according to specific simulation requirements. For example, if the simulation scenario does not consider changes in air composition at the fluid interface, the fluid interface may not include the composition parameter. For example, if the simulation scenario considers changes in air velocity at the fluid interface, the fluid interface may include the velocity parameter. For example, the interaction interfaces and interaction parameters are shown in the table below: Table 1 Interaction Interface and Interaction Parameters
[0032] In this embodiment, both the fluid interface and the mechanical interface are used as the interaction interfaces of the target wind turbine. This makes it easier to describe the changes in the fluid parameters of the fluid interface under different mechanical operating parameters of the mechanical interface, which is beneficial for the wind turbine twin model to be applicable to more simulation scenarios.
[0033] Step S20: Based on the interaction parameters, construct the control body model of the target wind turbine, wherein the control body model is used to describe the correspondence between the interaction parameters input to the target wind turbine and the output of the target wind turbine; It should be noted that the control volume model is used to describe the correspondence between the interaction parameters input to the target wind turbine and the output of the target wind turbine.
[0034] In this embodiment, a control volume model of the target fan can be constructed based on the correspondence between the mass, energy, and momentum of the input target fan and the target fan output using interaction parameters. Since the correspondence between the fluid parameters between the inlet and outlet of the target fan will change under different mechanical operating parameters such as rotational speed and power, this embodiment can obtain the fan operating curve corresponding to the target fan and the parameter input values of the interaction parameters at the fluid inlet side of the target fan. Then, based on the parameter input values and the fan operating curve, the parameter output values corresponding to the outlet side of the target fan can be calculated. Therefore, a control volume model of the target fan can be constructed based on the mapping relationship between the parameter input values and the parameter output values, thereby describing the correspondence between the input and output of the interaction parameters.
[0035] Step S30: Based on the interactive interface and control body model, build a wind turbine twin model corresponding to the target wind turbine for performing wind turbine simulation operations.
[0036] like Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of the wind turbine twin model involved in this application embodiment. The interaction interface includes a fluid interface and a mechanical interface. The fluid interface includes a fluid inlet and a fluid outlet. The fluid inlet is used to transmit the interaction parameters (such as inlet flow rate, inlet temperature, inlet pressure, etc.) corresponding to the fluid entering the target wind turbine. The fluid outlet is used to transmit the interaction parameters (such as outlet flow rate, outlet temperature, outlet pressure, etc.) corresponding to the fluid output by the target wind turbine. In this embodiment, the interaction interface can be used as a data interface for the control body model corresponding to the target wind turbine to interact with the outside world, thereby obtaining the wind turbine twin model corresponding to the target wind turbine. Thus, the wind turbine twin model can be used to perform wind turbine simulation operations. For example, after the data of the wind turbine twin model flows into the interaction interface, the parameter input values corresponding to the interaction parameters that can be input to the control body model are obtained. Then, the control body model performs calculations on the parameter input values to obtain the corresponding parameter output values, which are output through the interaction interface. Thus, this embodiment uses the wind turbine twin model to describe the changes of fluid under different control conditions before and after passing through the target wind turbine, thereby enabling accurate simulation of different wind turbine operating scenarios.
[0037] The first embodiment of this application provides a fan simulation method. This method involves determining the interaction interface of a target fan and the corresponding interaction parameters. Based on the interaction parameters, a control body model of the target fan is constructed, whereby the control body model describes the correspondence between the interaction parameters input to and output of the target fan. Based on the interaction interface and the control body model, a fan twin model corresponding to the target fan is built for executing fan simulation operations. Therefore, this embodiment describes the correspondence between the interaction parameters involved in the interaction between the target fan and the external environment, and constructs a fan twin model. This allows for the determination of fluid changes before and after passing through the target fan, achieving accurate simulation of the fan's operating scenario and effectively improving the product development efficiency of fans in water heaters.
[0038] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in the first embodiment described above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 3 Step S20 also includes steps S21 to S23: Step S21: Obtain the wind turbine operation curve and the parameter input values corresponding to the interaction parameters for the target wind turbine; Step S22: Based on the parameter input values and the fan operation curve, calculate the parameter output values of the target fan; Step S23: Based on the mapping relationship between parameter input values and parameter output values, construct the control body model of the target wind turbine.
[0039] It should be noted that the fan operating curve refers to the index values of the target fan under different mechanical operating parameters and corresponding to the interaction parameters, such as pressure ratio, power, and flow rate. The fan operating curve can be described in the form of a graph, function, mapping table, etc.
[0040] Due to differences in the structural design of different fan blades, ducts, motors, etc., different fans will have different operating curves. Therefore, in this embodiment, by obtaining the operating curve of the target fan, the index values of the target fan under different mechanical operating parameters and corresponding to the interaction parameters can be obtained to match the actual operating state of the target fan. The parameter input values corresponding to the interaction parameters are also obtained. These parameter input values refer to the parameter values input from components connected to the input side of the target fan, such as the fan speed and power, and the fluid temperature, pressure, and flow rate. Based on the parameter input values and the fan operating curve, the parameter output values of the target fan can then be calculated. For example, in this embodiment, the fluid flow rate can be obtained by substituting the fan speed into the fan operating curve. Since the fan does not store air inside, the inlet flow rate and outlet flow rate of the target fan are equal. Since the target fan may have multiple inlets on the fluid inlet side and multiple outlets on the fluid outlet side, the inlet sub-flow rate and outlet sub-flow rate of each inlet can be determined based on the cross-sectional area of each inlet and outlet. Then, a control volume model of the target fan can be constructed based on the mapping relationship between the parameter input values and the parameter output values. Therefore, the control volume model's description of the relationship between parameters at the fluid inlet and outlet more closely matches the actual operating curve of the target fan, effectively improving the accuracy of the control volume model.
[0041] In some embodiments, step S21 includes steps A10 to A30: Step A10: Obtain the speed characteristic data of the target fan, including the fan flow rate, fan pressure ratio and fan power of the target fan at each speed. Step A20: Create an original mapping table based on the fan flow rate, fan pressure ratio, and fan power at each speed. Step A30: Interpolate the original mapping table to obtain the corresponding wind turbine operating curve.
[0042] It should be noted that the rotational speed characteristic data includes the fan flow rate, fan pressure ratio, and fan power of the target fan at each rotational speed, which are associated with the interaction parameters. The fan flow rate is the mass flow rate of the fluid flowing through the target fan, the fan pressure ratio is the ratio between the outlet pressure and the inlet pressure of the fluid in the target fan, and the fan power is the output power of the target fan.
[0043] This embodiment can collect the fan flow rate, fan pressure ratio, and fan power of the target fan at various speeds in advance to obtain the speed characteristic data of the target fan. This embodiment can create an original mapping table based on the fan flow rate, fan pressure ratio, and fan power associated with the interaction parameters at each speed. Since the input inlet flow rate in actual scenarios has more detailed breakdowns, this embodiment can also obtain the corresponding fan operating curve by interpolating the original mapping table. Figure 4 As shown, the interpolation process can be based on the achievable ingress traffic M in the actual scenario. F Interpolation is performed to convert the achievable inflow flow M into... F After substituting into the original mapping table, the fan flow rate and the achievable inlet flow rate M are obtained. F The fan pressure ratio and fan power in the preceding and following adjacent speed characteristic data are linearly interpolated to obtain the interpolation result, which is the achievable inlet flow rate M. F The corresponding fan pressure ratio π and fan power P are used to add the interpolation results to the original mapping table to obtain the fan operating curve. Thus, this embodiment achieves the construction of the fan operating curve and can also reduce the calculation of invalid numerical nodes in subsequent operation of the fan operating curve, improving the efficiency of constructing the fan curve for the target fan.
[0044] In some embodiments, step S22 includes steps B10 to B50: Step B10: Based on the fan speed in the parameter input value, query the fan operation curve to obtain the fan flow rate at the fan speed as the outlet flow rate; Step B20: Calculate the total outlet temperature based on the inlet temperature in the parameter input values and the fan pressure ratio at the fan speed in the fan operation curve; Step B30: Calculate the outlet pressure based on the inlet pressure and fan pressure ratio in the parameter input values; Step B40: Calculate the work done per unit fluid based on the inlet temperature and the total outlet temperature; Step B50 outputs the outlet flow rate, total outlet temperature, outlet pressure, and work done per unit fluid as parameters.
[0045] In this embodiment, the fan speed in the parameter input value can be substituted into the fan operation curve to obtain the fan flow rate at that fan speed. This fan flow rate is then used as the outlet flow rate. It can be understood that when there are multiple outlets on the fluid outlet side of the target fan, the outlet sub-flow rate of each outlet can be determined based on the cross-sectional area of each outlet. The outlet sub-flow rate is positively correlated with the cross-sectional area of the outlet, and the sum of all outlet sub-flow rates is the total outlet flow rate. Of course, since the fan does not store air inside, the inlet flow rate and outlet flow rate of the target fan are equal. When there are multiple inlets on the fluid inlet side of the target fan, the inlet sub-flow rate of each inlet can be determined based on the cross-sectional area of each inlet. The inlet sub-flow rate is positively correlated with the cross-sectional area of the inlet, and the sum of all inlet sub-flow rates is the total inlet flow rate.
[0046] Since air undergoes temperature changes during compression and expansion, this embodiment can calculate the total outlet temperature based on the inlet temperature in the input parameters and the fan pressure ratio at the fan speed in the fan operation curve. For example, the formula for calculating the total outlet temperature is as follows: ; Among them, T t_out Total temperature at export; T t_in For inlet temperature; π c η is the fan pressure ratio at the fan speed; c The adiabatic efficiency of the fan is typically taken as 1; k is an adiabatic index factor that describes the fan pressure ratio π. c The degree of influence of temperature changes is typically about 1.4 for air or other diatomic ideal gases.
[0047] Since the fan pressure ratio at the fan speed in the fan operation curve describes the ratio between the inlet pressure and the outlet pressure, this embodiment can calculate the outlet pressure based on the inlet pressure and the fan pressure ratio in the parameter input values. The outlet pressure is the product of the inlet pressure and the fan pressure ratio.
[0048] Furthermore, this embodiment can also measure the relationship between heat change and temperature change of fluid under constant pressure using the isobaric specific heat capacity based on the inlet temperature and outlet total temperature, thereby calculating the energy consumed by the temperature change (i.e., work done per unit fluid) during the expansion or compression of each kilogram of air. For example, the formula for calculating the work done per unit fluid is as follows: ; Among them, T t_out Total temperature at export; T t_in Inlet temperature; C p Specific heat capacity at constant pressure; L c Work done per unit fluid.
[0049] Ultimately, this embodiment uses the outlet flow rate, the outlet total temperature, the outlet pressure, and the work done per unit fluid as the parameter output values. Thus, this embodiment constructs the corresponding relationship between the parameter input values and the fan operating curve to determine the required parameter output values at the fluid outlet of the target fan's fluid interface. This embodiment not only calculates the flow rate, temperature, and pressure of the fluid output from the target fan but also calculates the work done by the fluid on temperature changes during its passage through the target fan with relatively high precision, facilitating a more refined simulation of the target fan.
[0050] In the second embodiment of this application, the operating curve of the target fan and the parameter input values corresponding to the interaction parameters are obtained; based on the parameter input values and the fan operating curve, the parameter output values of the target fan are calculated; and based on the mapping relationship between the parameter input values and the parameter output values, a control body model of the target fan is constructed. Therefore, in this embodiment, the control body model's description of the relationship between parameters between the fluid inlet and fluid outlet more closely matches the actual operating curve of the target fan, effectively improving the accuracy of the control body model.
[0051] Based on the first embodiment of this application, in the third embodiment of this application, the content that is the same as or similar to that in the first embodiment described above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 5 The wind turbine simulation method described after S30 further includes steps C10 to C20: Step C10: Obtain target scene information, including the connection relationship between the target fan and the water heater components; Step C20: Based on the connection relationship, connect the fan twin model with the component twin model of the water heater component to achieve the simulation of the target scenario.
[0052] It should be noted that the water heater component is the part that is expected to be connected to the target fan in the target scenario.
[0053] like Figure 6As shown, in the fluid interface of the fan twin model, the fluid inlet is directly connected to the environment P, while the fluid outlet is connected to the flue, which in turn is connected to the environment P. The mechanical interface of the fan twin model can be connected to a controller to query the fan operating curve based on the rotational speed N, obtaining the corresponding fan flow rate, fan pressure ratio, fan power, etc. This embodiment can obtain target scene information, including the connection relationship between the target fan and the water heater component; based on the connection relationship, the fan twin model is connected to the component twin model of the water heater component to achieve the simulation of the target scene. Since the fan twin model in this embodiment does not perform the modeling of the entire device as in traditional twin models, but rather models a single component in the overall device independently, the connection of the water heater component required by the fan twin model can be adjusted according to specific needs, thus making it applicable to more different simulation scenarios and more widely applicable.
[0054] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the wind turbine simulation method of this application. Any simple modifications based on this technical concept are within the protection scope of this application.
