Description

Technical Field

[0001] The invention relates to the technical field of water conservancy data processing, and in particular to a method for calculating the energy dissipation rate of an energy dissipation well. Background Art

[0002] In today's society, pipeline water delivery has become a common water delivery method for many water diversion projects, which can effectively reduce water leakage and evaporation and avoid pollution of the surrounding environment along the pipeline. However, there are also some inevitable problems with pipeline water delivery. Long-distance water diversion projects often have large height differences, resulting in the pipeline pressure head far exceeding the energy consumed along the pipeline. The excessive water flow pressure is extremely harmful to the safety of the pipeline and the buildings and environment of the outlet. Therefore, it is necessary to eliminate the excess energy of the pipeline water flow through energy dissipation means. Energy dissipation wells are a common way to dissipate energy for pipeline water delivery. Energy dissipation wells can effectively reduce the scouring of the outlet and the size of the water hammer. At the same time, energy dissipation wells can realize segmented energy dissipation of the pipeline, ensuring that the front and rear sections of the pipeline operate independently, and the burst and uncontrolled pipeline will not affect the other section of the pipeline. Therefore, the application of energy dissipation wells is of great significance to water conservancy projects.

[0003] Energy dissipation wells play a role in eliminating water flow energy, and the evaluation or calculation of their energy dissipation rate is worth studying. When calculating the energy dissipation rate of traditional energy dissipation wells, usually only the head loss in the energy dissipation well is calculated, ignoring the head loss at the water inlet or outlet. In order to facilitate the calculation of the energy dissipation rate, the water inlet and outlet of the energy dissipation well are set on the same horizontal plane. However, in actual settings, there may be situations where the water inlet and outlet are not on the same horizontal plane. It is necessary to consider the energy consumed by the water inlet and outlet and the energy consumed by the height difference. In this case, the traditional calculation result of the energy dissipation rate of the energy dissipation well is not accurate. Summary of the invention

[0089] In today's society, pipeline water delivery has become a common water delivery method for many water diversion projects, which can effectively reduce water leakage and evaporation and avoid pollution of the surrounding environment along the pipeline. However, there are also some inevitable problems with pipeline water delivery. Long-distance water diversion projects often have large height differences, resulting in the pipeline pressure head far exceeding the energy consumed along the pipeline. The excessive water flow pressure is extremely harmful to the safety of the pipeline and the buildings and environment of the outlet. Therefore, it is necessary to eliminate the excess energy of the pipeline water flow through energy dissipation means. Energy dissipation wells are a common way to dissipate energy for pipeline water delivery. Energy dissipation wells can effectively reduce the scouring of the outlet and the size of the water hammer. At the same time, energy dissipation wells can realize segmented energy dissipation of the pipeline, ensuring that the front and rear sections of the pipeline operate independently, and the burst and uncontrolled pipeline will not affect the other section of the pipeline. Therefore, the application of energy dissipation wells is of great significance to water conservancy projects.

[0090] Energy dissipation wells play a role in eliminating water flow energy, and the evaluation or calculation of their energy dissipation rate is worth studying. When calculating the energy dissipation rate of traditional energy dissipation wells, usually only the head loss in the energy dissipation well is calculated, ignoring the head loss at the water inlet or outlet. In order to facilitate the calculation of the energy dissipation rate, the water inlet and outlet of the energy dissipation well are set on the same horizontal plane. However, in actual settings, there may be situations where the water inlet and outlet are not on the same horizontal plane. It is necessary to consider the energy consumed by the water inlet and outlet and the energy consumed by the height difference. In this case, the traditional calculation result of the energy dissipation rate of the energy dissipation well is not accurate.

[0091] The present invention obtains water inlet parameters, well parameters and water outlet parameters of the energy dissipation well, calculates the water head loss at the water inlet, the water head loss in the well and the water head loss at the water outlet, calculates the energy dissipation rate through the three head losses, and improves the accuracy of the energy dissipation rate calculation of the energy dissipation well.

[0092] A method for calculating the energy dissipation rate of energy dissipation wells, such as Figure 1 As shown, the following steps are included:

[0093] S1, obtaining water inlet parameters, well parameters and water outlet parameters of the energy dissipation well;

[0094] S2, establishing the energy equation according to the water inlet parameters, well parameters and water outlet parameters;

[0095] S3, calculate the head loss according to the energy equation;

[0096] S4, calculate the energy dissipation rate based on the head loss;

[0097] Among them, head loss includes: head loss at the water inlet, head loss in the well and head loss at the water outlet.

[0098] It should be noted that the water inlet parameters are the parameters of the water inlet pipe of the energy dissipation well, including pipe parameters and water flow parameters, the well parameters are the parameters inside the energy dissipation well, and the water outlet parameters are the parameters of the water outlet pipe of the energy dissipation well, including pipe parameters and water flow parameters. The three parameters can be obtained by installing sensors in the existing energy dissipation well to calculate the energy dissipation rate of the energy dissipation well, or a certain proportion of parameters can be obtained according to the establishment of a simulation model for the energy dissipation well project to be implemented, and the energy dissipation rate of the energy dissipation well can be evaluated. Head loss is the loss of water flow energy due to various reasons during the water flow transportation process. The head loss of this embodiment includes the head loss at the water inlet, the head loss in the well, and the head loss at the water outlet.

[0099] In this embodiment, the water inlet parameters, well parameters and water outlet parameters of the energy dissipation well are obtained to calculate the head loss at the water inlet, the head loss in the well and the head loss at the water outlet. The energy dissipation rate is calculated based on the three head losses to improve the accuracy of the energy dissipation rate calculation of the energy dissipation well.

[0100] In some embodiments, in step S2, an energy equation is established based on water inlet parameters, well parameters, and water outlet parameters, such as Figure 2 As shown, the following steps are included:

[0101] S21, establishing a first energy equation according to water inflow parameters and well parameters;

[0102] S22, establishing a second energy equation according to the water inlet parameters, the well parameters and the water outlet parameters;

[0103] S23, establishing a third energy equation according to the well parameters and the water output parameters;

[0104] Among them, the water inlet parameters include: water inlet height, water inlet pressure and water inlet flow rate;

[0105] Well parameters include: well water level, well pressure and well flow rate;

[0106] The water outlet parameters include: outlet height, outlet pressure and outlet flow rate.

[0107] It should be noted that the first energy equation is established based on the water inlet parameters and the parameters in the well, which takes into account the head loss of water passing through the water inlet pipe and entering the energy dissipation well through the water inlet; the second energy equation is established based on the water inlet parameters, the parameters in the well and the water outlet parameters, which takes into account the head loss of water passing through the inside of the energy dissipation well; the third energy equation is established based on the parameters in the well and the water outlet parameters, which takes into account the head loss of water passing through the water outlet pipe and entering the water outlet pipe through the water outlet. In this embodiment, the water inlet is set in the middle of the energy dissipation well, and water flows toward the bottom of the energy dissipation well. After impacting the bottom of the energy dissipation well, the water flow moves in the opposite direction to the water outlet, during which part of the energy is lost due to movement and collision. Therefore, the horizontal height of the water outlet is greater than or equal to the horizontal height of the water inlet to ensure the head loss inside the energy dissipation well.

[0108] In some embodiments, the first energy equation is expressed as follows:

[0109]

[0110] in, is the water inlet pressure, is the density of water, is the acceleration due to gravity, is the water inlet correction coefficient, is the water inlet flow rate, is the well pressure, is the well correction coefficient, is the flow velocity in the well, is the water inlet head loss coefficient;

[0111] The second energy equation is expressed as follows:

[0112]

[0113] in, is the well pressure, is the density of water, is the acceleration due to gravity, is the well correction coefficient, is the flow velocity in the well, is the water level in the well, is the outlet height, is the water inlet height, is the water inlet head loss coefficient, is the head loss coefficient in the well;

[0114] The third energy equation is expressed as follows:

[0117] In some embodiments, step S3 calculates the head loss according to the energy equation, such as Figure 3 As shown, the following steps are included:

[0121] The water inlet head loss coefficient is expressed as follows:

[0122]

[0123] in, is the water inlet head loss coefficient, is the water inlet pressure, is the density of water, is the water inlet flow rate, is the water inlet correction coefficient, is the well pressure, is the well correction coefficient, is the flow rate in the well;

[0124] The head loss coefficient in the well is expressed as follows:

[0125]

[0126] in, is the head loss coefficient in the well, is the well pressure, is the density of water, is the water inlet flow rate, is the well correction coefficient, is the flow velocity in the well, is the acceleration due to gravity, is the water level in the well, is the water inlet height, is the water inlet pressure, is the water inlet correction factor;

[0128]

[0129] in, is the outlet head loss coefficient, is the acceleration due to gravity, is the water level in the well, is the outlet flow rate, is the outlet height, is the outlet pressure, is the density of water, is the outlet correction factor.

[0130] It should be noted that the water inlet head loss coefficient is the proportional coefficient of energy loss after the water flows through the water inlet, the water head loss coefficient in the well is the proportional coefficient of energy loss after the water flows through the inside of the energy dissipation well, and the water outlet head loss coefficient is the proportional coefficient of energy loss after the water flows through the outlet pipe. In this embodiment, the water inlet correction coefficient, the water outlet correction coefficient and the well correction coefficient are the corresponding kinetic energy loss correction coefficients, which are usually taken as 1.

[0131] In some embodiments, step S4 calculates the energy dissipation rate based on the head loss, such as Figure 4 As shown, the following steps are included:

[0132] S41, summing the water head loss coefficient of the water inlet, the water head loss coefficient in the well and the water head loss coefficient of the water outlet to obtain the water head loss coefficient,

[0133] S42, calculate the energy dissipation rate based on the head loss coefficient;

[0134] The head loss coefficient is expressed as follows:

[0135]

[0136] in, is the head loss coefficient, is the water inlet head loss coefficient, is the head loss coefficient in the well, is the outlet head loss coefficient.

[0137] It should be noted that the head loss coefficient is the sum of the head loss coefficient at the water inlet, the head loss coefficient in the well, and the head loss coefficient at the water outlet, which measures the total energy loss of the water flow. The energy dissipation rate of the energy dissipation well can be obtained by calculating the ratio of the energy at the water inlet pipe to the energy lost.

[0138] In some embodiments, the energy dissipation rate is expressed as follows:

[0139]

[0140]

[0141]

[0142] in, is the energy dissipation rate, is the energy at the water inlet, is the energy at the water outlet, is the head loss coefficient, is the water inlet flow rate, is the acceleration due to gravity, is the water inlet pressure, is the density of water.
