BOUNDARY LAYER FLOW AND HEAT TRANSFER OF A DUSTY FLUID OVER A VERTICAL PERMEABLE STRETCHING SURFACE

Runu Sahu, S.K.Mishra

Abstract: The steady boundary layer free convective flow of a dusty fluid past a vertical permeable stretching surface is studied .The governing equations are converted into first order ordinary differential equations using similarity transformations. These equations are solved numerically by using Runge kutta forth order method. The effects of physical parameters like fluid-particle interaction parameter, local Grashof number, suction parameters, Prandtl number, radiation parameter and Eckert number on the flow and heat transfer characteristics are computed and presented graphically. Also the rate of heat transfer at the surface is discussed. The present results are compared with the previous study and there is a good agreement
