Abstract:

 

This paper considers exact solutions of unsteady free  convection flow with thermal radiation past a vertical porous plate  with Newtonian heating.  The technique of Laplace transform was  employed in deriving the solutions to the governing flow and energy  equations.  A parametric study of all parameters involved was  conducted, and a representative set of results showing the effect of  the radiation parameter N, the ratio of uniform suction to  characteristic velocity parameter R, and the free convection parameter  Gr on the velocity and temperature are illustrated graphically.  The  skin friction or shear and heat flux are discussed quantitatively.  It  is evident that the results reveal the characteristics of the problem.
