[0054] In the embodiments of the present disclosure, the collection, storage, use, processing, transmission, provision and disclosure of user personal information involved are in compliance with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0055] Example 1

[0056] With the advancement of science and technology, the combination of simulation and experiment is widely used in product development. For different products, it is necessary to build unique geometric models and numerical models according to the use environment to obtain more accurate simulation results. This embodiment is a simulation evaluation method specifically for burner ignition performance. Figure 1 As shown, the ignition performance evaluation method includes:

[0057] S1. Construct a simulation model of the burner of a gas stove.

[0058] The simulation model includes the geometric model and numerical model of the burner. The geometric model is used to simulate the combustion conditions of the gas stove. The numerical model is used to simulate the flow field conditions of the burner according to the physical phenomena occurring during the combustion process.

[0059] In an optional embodiment, step S1 includes:

[0060] S101, determining the solid area of ​​the burner according to the fire cover, the ignition needle, the liquid receiving tray, the distance between the liquid receiving tray and the pot bottom, and the side wall of the burner.

[0061] S102. Determine the air domain of the burner within a preset multiple space range of the solid domain according to the type of gas and the inlet pressure of the gas.

[0062] Figure 2 This is the physical model of the burner ignition flow field of this embodiment. The air domain is about 10 times the solid domain, the bottom area is the area of ​​the liquid tray, and the height is the distance between the liquid tray and the bottom of the pot. Figure 3 It is a schematic diagram of an air inlet 31 and an air-gas mixture inlet 32 ​​. The air inlet 31 is arranged on the side walls around the burner.

[0063] S103, determining the number of grids in the solid domain and the air domain respectively according to the grid analysis speed, the grid quality and the accuracy of the burner parts to be simulated.

[0064] Among them, the mesh quality and the simulation accuracy of the burner parts are positively correlated with the number of meshes, and the mesh analysis speed is negatively correlated with the number of meshes. The mesh quality includes the mesh orthogonal quality and the topological mesh quality.

[0065] In actual operation, the number of grids is set for the parts of the burner respectively, and the number of grids is increased for the small-sized parts and the parts that need special attention, such as increasing the number of grids for the fire cover.

[0066] S104. Divide the solid domain and the air domain by meshing according to the number of meshes to construct a geometric model of the burner.

[0067] The geometric model of the burner after meshing is as follows: Figure 4 As shown. In a specific example, the mesh density is distributed at the fire cover and nozzle positions, where the number of tetrahedral meshes is about 7.5 million and the mesh orthogonality quality is greater than 0.11. In the analytical software, after converting the tetrahedral mesh into a polyhedral mesh, the mesh can be reduced to one eighth of the previous number, but at the same time, the topological mesh quality must be greater than 0.1 to avoid the analysis not converging due to poor mesh quality.

[0068] In an optional implementation, step S1 further includes:

[0069] S111. Construct a numerical model of the burner based on the turbulence model, wall function, heat transfer and radiation model, component transport model and boundary conditions.

[0070] In a specific example of a steady-state pressure-based solution where the fluid materials of the model include air and natural gas, the simulation model of the burner is as follows Figure 5 As shown, Figure 6 It is a schematic diagram of the burner gas-air mixture inlet. The numerical model of this example is provided with an air pressure inlet, an air-gas mixture flow inlet, and a pressure outlet. Among them, the air inlet pressure is 0 Pa (Pascal, a unit of pressure), and the pressure of the pressure outlet is 0 Pa. Furthermore, the air-gas mixture flow inlet can be divided into the first mixture inlet (inner ring flow inlet), the second mixture inlet (middle ring flow inlet), and the third mixture inlet (outer ring flow inlet) according to the number of independent channels of the burner, wherein the flow data can be read from the one-time injection simulation results of the burner at the entrance of the mixing chamber. The burner in this example has three independent gas channels, wherein the flow rate of the first mixture inlet is 5.6782e -5kg / s (kilograms per second), the flow rate of the second mixed gas inlet is 0.0003kg / s, the flow rate of the third mixed gas inlet is 0.00068kg / s, the components and component masses of each mixed gas inlet are the same, and the mass fractions of the components in this example are as follows: CH4 (methane): 0.075, O2 (oxygen): 0.211, N2 (nitrogen) 0:0714.

[0071] The turbulence model in this example is the Realizable k-ε model (an improved version of the standard k-ε model, used to predict fluid flow characteristics), the wall function is the Standard Wall Functions (a method used in computational fluid dynamics to deal with flow near the wall), the component transport equation is the Transport species, and the energy source term is expanded. The default settings of Solution Methods are as follows Figure 7 As shown in the figure, the scheme is simple (a widely used pressure-velocity coupling algorithm), the pressure is presto! (a pressure interpolation scheme), the components are all second-order calculations, and the other settings are kept as default based on historical experience.

[0072] S2. In response to the combustion of the burner, the average mass fraction of methane and the combustion velocity of the monitoring surface of the burner are obtained through the simulation model.

[0073] In an optional embodiment, the monitoring surface includes at least one of an circumscribed arc surface of a preset angle ignition diameter, a midpoint arc surface of a preset angle ignition diameter, and an inscribed arc surface of a preset angle ignition diameter provided on the burner.

[0074] The settings of the preset angle ignition diameter circumscribed arc surface 501, the preset angle ignition diameter midpoint arc surface 502, and the preset angle ignition diameter inscribed arc surface 503 of the burner are as follows: Figure 8 shown.

[0075] Among them, Fig. 9 The preset angle 601 shown is within a range of plus or minus 6 degrees from left to right along the arrow direction from the center point of the ignition needle.

[0076] S3. In response to the surface average mass fraction of methane falling within the first numerical range and the combustion speed falling within the second numerical range, the ignition performance of the burner is evaluated as excellent.

[0077] Among them, the first numerical interval can be set to 0.04~0.06, and the second numerical interval can be set to 0.2~0.35 m / s. That is, if the average mass fraction of methane falls within 0.04~0.06 and the combustion speed falls within 0.2~0.35 m / s, the ignition performance of the burner is evaluated as excellent.

[0078] In an optional embodiment, the ignition performance evaluation method further includes:

[0079] S4. In response to the surface average mass fraction of methane not being within the first numerical interval, or the combustion velocity not being within the second numerical interval, the ignition performance of the burner is evaluated as unqualified.

[0080] In this embodiment, the simulation model of the burner of the gas stove is used to simulate the actual situation of the burner combustion, so as to obtain simulation results that conform to the actual burner ignition conditions, thereby improving the efficiency of the burner ignition evaluation and improving the accuracy of the burner ignition evaluation results.

[0081] In an optional embodiment, step S4 includes:

[0082] S41. Obtain a physical field cloud map of the burner.

[0083] The physical field cloud map includes at least one of the combustion velocity, pressure, density, and component concentration of the burner.

[0084] S42. Analyze the area of ​​the burner to be optimized through the physical field cloud map.

[0085] In this embodiment, when the ignition performance of the burner is unqualified, the area to be optimized of the burner is analyzed through a physical field cloud map, so that it is convenient for R&D personnel to further optimize the area to be optimized and improve R&D efficiency.

[0086] In a specific example, the physical field cloud diagrams of the preset angle ignition diameter inscribed arc surface, the preset angle ignition diameter midpoint arc surface, and the preset angle ignition diameter circumscribed arc surface of the burner are respectively as follows: Fig.10 , Fig.11 as well as Fig.12 As shown. From the physical field cloud diagram of the burner, we can get Fig.13 and Fig.14 The average mass fraction curve of methane surface for different types of burners is shown in Figure 2. Fig.15 and Fig.16 The methane velocity curves of different burner models are shown in Figure 2. Fig.13 and Fig.15 Corresponding to the same model burner, Fig.14 and Fig.16 Corresponding to the same type of burner). Finally, the optimizable area 141 is determined as follows Fig.17 The characteristic surface methane concentration distribution cloud map is shown. It should be noted that the methane surface average mass fraction curve is the methane surface average mass fraction calculated based on the methane concentration of the characteristic surface methane concentration distribution cloud map. The methane velocity curve is the surface average velocity calculated based on the methane velocity of the characteristic surface methane concentration distribution cloud map.
