G050034 Effects of Coriolis' Force on Vortex in Cylindrical Vessel

Abstract

The cylinder rotating around horizontal axis was put on the table rotating around vertical axis. The inclination and collapse phenomena of the vortex were observed while changing the speed of rotating table and rotating cylinder, the length of test section of cylinder and viscosity of test fluid in this experiment. The vortex in the rotating cylinder inclined in the directions upper right or lower right by the effects Coriolis' force. As the speed of rotating table was increased, the vortex collapsed. But when the viscosity of test fluid was high, it did not collapse even if the speed of rotating table was increased.
