Free convection effects on the stokes problem for an infinite vertical limiting surface with constant suction

This paper studies the effects of free convection currents on the flow field of an incompressible viscous fluid past an impulsively started infinite vertical porous limiting surface when the fluid is subjected to a suction with uniform velocity. An exact analysis of the problem is obtained with the aid of the Laplace transform technique and the expressions for the velocity field, temperature field and for their related quantities of skin friction and rate of heat transfer are given. The results thus obtained are discussed quantitatively for air and water.
