The flow is symmetric with respect to the inter-disk midplane as well as axisymmetric around the axis of rotation at small Reynolds numbers. It becomes unstable to two different modes of disturbance, one of which is an axisymmetry-breaking mode to yield a polygonal flow pattern in the radial tangential plane and the other is a symmetry-breaking instability with respect to the inter-disk midplane with retaining the axisymmetry. The symmetry-breaking mode of instabilty was analyzed numerically assuming the axisymmetry and it was found that the steady axisymmetric flow is unstable not only to stationary disturbances but also to oscillatory disturbances. Bifurcation diagrams of the flow for various values of gap ratio were obtained and a transition diagram was depicted. Numerical results are confirmed by experiments., 資料番号: AA0047776016, レポート番号: JAXA-SP-04-002}, pages = {51--54}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {静止円筒容器中で回転する2円板間流れの遷移}, volume = {JAXA-SP-04-002}, year = {2005} }
