似乎我们需要一个模型来适应停滞区域的层流，并在距离该区域一定距离的地方变成湍流模型。具有转换功能的单一模型将会更好。建立了二维轴对称CFD（计算流体动力学）模型，模拟了双盘间通道内90度转向径向流动的UMN试验台。本文对单向流和振荡流的S（盘间距）= 0.127 m和ReD =7600的情况进行了研究。
It seems that we need a model that will accommodate laminar flow in the stagnation region and turn into a turbulent model some distance away from this region. A single model with transition capabilities will be even better. A 2-D axisymmetric CFD (Computational Fluid Dynamics) model was developed to simulate the UMN test rig with a 90-degree flow turn to a radial flow in a channel between two discs. One case has been examined in this paper, S (Disc spacing) = 0.127 m and ReD =7600 for both unidirectional and oscillatory flows.
