Abstract

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.
基于UDF程序的恒流节水器CFD分析与优化
采用仿真分析与实验测试相结合的方法,对恒流节水器在不同水压下的出水流量控制进行了研究。对交通影响的研究。建立的基于UDF程序的气液两相流-液CFD瞬态分析流程与试验结果误差小于5%,可为恒流节水器的设计改进和优化提供指导。为了提高计算效率,研究了相应的稳态分析过程。结果表明,与瞬态分析过程相比,稳态分析过程的精度可达95%以上,计算效率可提高一倍。
