Abstract:
The present investigation deals with the effects of hall current, and Soret number on the non linear, radiative, unsteady, hydromagnetic natural convection flow of an optically thick rotating fluid past an impulsively started vertical porous plate. Exact analytical solution of the non-dimensional governing equations is obtained in closed form by using Laplace transform technique. The numerical values of primary and secondary velocity profiles are displayed graphically for different values of pertinent flow parameters.
