CFD analysis and optimization of constant flow water saver based on UDF program

Using the method of combining simulation analysis and experimental test, research on the control of the effluent flow under different water pressures of a constant-flow water saver was carried out. A study of the impact of traffic. The established gas-liquid two-phase flow-liquid CFD transient analysis process based on the UDF program has an error of less than 5% with the test results, which can provide directions for the design improvement and optimization of the constant-flow water saver. In order to improve the calculation efficiency, the corresponding steady-state analysis process is studied. The results show that, compared with the transient analysis process, the accuracy of the steady-state analysis process is over 95%, and the calculation efficiency can be doubled.
