The conclusions are as follows. Rotation frequencies of disturbances do not so depend on the ratio of the outer- to the inner-sphere rotating Reynolds number if they are non-dimensionalized by the mean rotation frequency of both spheres. Herring-bone waves and wavy shear waves appear with increasing rotation effect for the co-rotating spheres, while spiral vortices and twists appear with increasing shear effect for the counter-rotating spheres. Flow regimes and their occurrence-region in the plane of the inner- and outer-sphere rotating Reynolds numbers differ by the Reynolds-number history., 資料番号: AA0032827006, レポート番号: NAL SP-54}, pages = {21--24}, publisher = {航空宇宙技術研究所, National Aerospace Laboratory (NAL)}, title = {独立に回転する同心2球間の流れ}, volume = {54}, year = {2002} }
