台阶突扩三维粘性流动数值模拟

3-D numerical simulation for the flow over a backward-facing step

    摘要
  • 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，表明所建立的三维粘性流动数学模型具有较强的模拟能力和较高的计算精度。

     

    Abstract: 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.
