本文采用点涡、Prandtl-Batchelor流和reynolds -average Navier-Stokes方程等模型对涡流捕获腔内的流动进行了模拟。其范围是确定无粘模型在多大程度上可以用于设计旋涡单元。结果表明，当伯努利常数在分界流线上适当跳跃时，Prandtl-Batchelor流给出了由reynolds -average Navier-Stokes方程得到的解的可接受的表示，当选择合适的湍流模型时，它又与实验结果相比较。
The flow inside a vortex trapping cavity is simulated by a suite of models: point vortex, Prandtl-Batchelor flow, and Reynolds-averaged Navier-Stokes equations. The scope is to ascertain to what extent an inviscid model can be used to design vortex cells. It turns out that the Prandtl-Batchelor flow, with an appropriate jump in the Bernoulli constant across the dividing streamline, gives an acceptable representation of the solution found by the Reynolds-averaged Navier-Stokes equations, which in turn compares well with experimental results when an appropriate turbulence model is selected.
