Competition of Linear Modes in a Spherical Couette Flow after Sudden Increase of Rotational Velocity of the Inner Sphere

摘要

Therefore, at intermediate points in time until the flow reaches the steadystate mode, the ratio of incre ments of increase of linear modes with azimuthal numbers of three and four varies compared to the case of steadystate boundary conditions on increasing Reinit. This allows one to explain the experimentally observed effect of the change of the mode of the sec ondary flow in rotating spherical layers with accelera tion from various initial states.
