Unsteady boundary layer flow of a micropolar fluid near the rear stagnation point of a plane surface

The growth of the boundary layer flow of a viscous and incompressible micropolar fluid started impulsively from rest near the rear stagnation point of a two-dimensional plane surface is studied theoretically. The transformed non-similar boundary-layer equations are solved numerically using a very ef...
