项目摘要

The flows around a rotating disk in a cylindrical casing and the flows between vertical coaxial cylinders are examined and the flow control method to obtain a optimal states is established. In the flow around the rotating disk, a variety of flow modes that originate from the radial clearance between the disk rim and the shroud and depend on the Reynolds number and the flow configuration are specified and classified. At the high Reynolds numbers, the interaction between the flow in the radial clearance and the spiral rolls in the disk region is investigated. In the flow between rotating cylinders, the transient Reynolds numbers at which the secondary flows transit to the primary flows are determined. These results give a new insight into the investigation of the dynamical mechanics in the three-dimensional rotating flows and contribute to provide control conditions to attain favorable flows.

本文研究了圆柱壳内旋转圆盘的绕流和同轴垂直圆柱间的绕流，建立了获得最佳状态的流动控制方法。在旋转盘的绕流中，各种流动模式，起源于盘边缘和护罩之间的径向间隙，并取决于雷诺数和流动配置指定和分类。在高雷诺数条件下，研究了径向间隙中的流动与盘区螺旋辊的相互作用。在旋转圆柱间的流动中，确定了二次流过渡到一次流的瞬态雷诺数。这些结果为三维旋转流动的动力学机理研究提供了新的思路，并为获得有利流动提供了控制条件。
