MRS criterion for flow separation over moving walls
Abstract
Steady, incompressible, laminar boundarylayer flows over moving walls are numerically investigated with special regard to the MRS criterion for flow separation. To analyze separated flows without meeting any singularity at the separation point, a set of approximate equations (instead of the boundarylayer equations) is solved under the condition of prescribed external velocity distributions. Three different types of flows are considered, one of which is quite similar to that treated by Tsahalis. It is found that, at least for the flows treated in the present paper, the MRS criterion is not satisfied for the case of upstreammoving walls, although it is satisfied for the case of downstreammoving walls.
