Boundary-Layer Similarity Solutions for Rotating Flows with and without Magnetic Interaction

Abstract
The laminar boundary layer produced by the rotating flow of a viscous incompressible fluid over a stationary infinite disk is considered. The external velocity is assumed to be tangential and to vary as some power of the radius, i.e., vrn. The case in which the fluid is electrically conducting and interacting with a magnetic field aligned with the axis of the disk is also considered. Boundary‐layer similarity equations, containing the parameter n and a magnetic interaction parameter are derived. Solutions for n between plus one (solid‐body rotation) and minus one (the potential vortex) are investigated.
