Rotating disk on an air chusion
Abstract
It is shown that selfrotation of the fluid occurs for a specific critical suction value of a viscous incompressible fluid through a porous disk situated above a fixed plane. Multicellular regimes connected with the suction are found to exist where the force acting on the rotating disk is a lift force and is anomalously large. Maps of possible steadystate flow regimes are constructed. A stable selfoscillatory regime is observed for sufficiently intense suction and rotation.
