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.

研究了圆柱机匣内旋转盘的绕流和垂直同轴圆柱间的流动，建立了获得最优状态的流动控制方法。在旋转圆盘周围的流动中，由圆盘边缘与叶冠之间的径向间隙产生的、依赖于雷诺数和流动构型的各种流动模式被规定和分类。在高雷诺数条件下，研究了径向间隙内的流动与盘区螺旋辊的相互作用。在旋转圆柱间流动中，确定了二次流过渡到一次流时的瞬态雷诺数。这些结果为研究三维旋转流动的动力力学提供了新的视角，并有助于为获得有利流动提供控制条件。
