Asymptotic behaviour of the laminar boundary layer flow of an incompressible fluid past a flat plate

Here the asymptotic behaviour, as the similarity variable 'eta' tends to in finity, of the solutions of the differential equations governing the lamina r boundary layer flow of an incompressible fluid past a flat plate embedded in a saturated porous medium have been studied based on the method of asym ptotic integrations of second order linear differential equations. It has b een found that the principal solutions exhibit asymptotic behaviour as eta --> infinity, whereas the independent solutions do not.
