| 摘 要： | 本文描述了旋转管流的基本运动方程。在笛卡尔坐标系和柱坐标系中,针对两种基本的几何流动,推导出旋转情况下管内的流动方程,定义了影响旋转管流的流动和换热的两个无量纲准则数J和Ra,分析了二次流产生的原因,从而说明旋转对流动的影响以及旋转管流的运动特征。

| Abstract: | This paper describes the basic equation in the rotating channels with cartesior coordinates and cylindrical coordinates. The non-dimensional number / (rotational number) and Ra (rotational Rayleigh Number) are defined from the differential equations. Meanwhile there is a secondary flow in the rotating tube, which effects the characteristic of flow. So that secondary flow is analysed in detail in this study. |
