An Approximate Method for Curved Shear Layers

Steady, incompressible two-dimensional laminar boundary layers on curved surfaces with spanwise rotation are investigated using an approximate method. A fourth-degree polynomial is assumed for the velocity profiles and they are found to constitute a three-parameter family of curves characterized by a pressure factor, a curvature parameter and a rotational parameter. The results obtained for constant surface velocity flow with/without rotation on plane/curved surfaces are found to be consistent with those reported in the literature.
