切变流体和旋转流体的动力学相似性

The Dynamic Similarity between Sheor Flow and Rotation Flow

在传统长重力波方程中引入水平基流的作用，导出了带有基流切变效应的平面波解．正如层结流体与旋转流体具有动力学相似性一样，发现切变流体也有类似的动力学相似性．

Based on the equations for long gravity waves,plane wave solution with the effect of basic shear flow has been derived.At the same time,the dynamic similarity between shear flow and rotation flow is also obtained.It is important to us in studying the properties of shear flow.
