基于流动控制原理,将文丘里效应应用到均速管流量计中,建立了几种双体均速管模型。通过数值分析不同模型的流量系数及其引起的永久压损随速度的变化规律,并与威力巴原型进行比较,从中选取最优模型。

In this paper,on the basis of the flow control theory, several tow-profile averaging pitot tube models by the Venturi effect applied to the averaging pitot tube were proposed.The variations of the flow coefficient and the permanent pressure loss with flow verocity on different models were numerically analyzed and the best model was obtained compared to the original Veris bar.
