转动管道内流体动力学方程及流动特性分析

Fluid Dynamic Equntion of Rotating Pipe and Flow Characteristic Analysis

从相对运动出发,导出了管道在转动情况下管内流体流动矢量形式的动力学方程,并在直角坐标和圆柱坐标系内,对平行和垂直于流动方向转动的两种基本情况进行了投影,定性地分析了与静止管流的差异所在。

On the basis of relation motion, a vectorial dynamic equation for fluid that flows through a rotating pipe is derived, which is then projected on cartesian coordinates and cylindrical coordinates in consideration of that the rotating axes are parallel and normal to the flow. The differences between rotating pipe flow and static pipe flow are analyzed quantitatively.
