Unsteady axisymmetric boundary-layer equations: Transformations, properties, exact solutions, order reduction and solution method

摘要

The paper deals with equations describing the unsteady axisymmetric boundary layer on a body of revolution. The shape of the body is assumed to be arbitrary. The axisymmetric boundary-layer equation for the stream function is shown to reduce to a plane boundary-layer equation with a streamwise-coordinate-dependent viscosity of the form
