基于CFD的倒流防止器压力损失研究

Study on Pressure Loss of Backflow Preventer Based on CFD

市政管网及生活饮用水管道中倒流防止器压力损失与可靠性一直是近年来水行业的热点问题,基于计算流体力学(CFD)方法,建立了倒流防止器内部流道三维模型,研究了不同工况下倒流防止器内部流场压力的损失及其变化规律,并通过搭建试验平台对模拟计算结果进行了验证。

The pressure loss and reliability of the backflow preventer in municipal pipe networks and drinking water pipelines have been a hot issue in the water industry in recent years.Based on the CFD method,the 3-D model of internal flow channel of the preventer was established,the pressure loss and its variation rule of the backflow preventer under different working conditions were studied,and the simulation results were verified through the test bench established.
