Effects of Rotation on a Turbulent Jet Flow over a Cylinder

In all of the experimental and theoretical work done on wall jets(1-3), the flow always passed over a stationary surface. An exception to this is the theoretical analysis reported in ref. 4 in which a laminar axi-symmetric jet impinged on a rotating disc. The present investigation aims to provide information on the flow of a turbulent jet over a rotating cylinder. The curvature of the wall, the jet slot width and the initial speed of the jet are kept constant. The speed of rotation is the important variable.
