The effect of turbulent models on the precision of numerical simulation of valves

ZHANG Zheng-yu1,ZHANG Zhi-quan2,WU Xianglian1,ZHU Wen-bing2(1.JiaXing Vocational Technical College,Jiaxing 310000,China;2.ZheJiang Provincial Bureau of Quality and Technical Supervision,Jiaxing 310000,China)  
The constant flux gas valve with bi-baffle structure was simulated numerically,using three different kinds of turbulent model.At the same time,a special high-accuracy experimental bench was built to compare the accuracy of different turbulent models.The comparison shows that the standard model has poor prediction accuracy and the results of and turbulent model is closer to the experiment ones.
