摘要
利用三维粘性流动数学模型 ,研究了台阶突扩流动的三维特性 .不同的雷诺数Re情况下 ,计算所得的流态、流速和压力分布与B .F .Amarly等的试验和计算结果相吻合 。
The characteristics of the flow over a backward facing step are studied by use of a 3 D viscous flow mathematical model. Based on the model, the calculated results of the flow pattern and distributions of velocity and pressure with different Re are agreeable with those of the experiment and calculation by B.F.Armaly. The model can well simulate the flow with high accuracy.
