Abstract

The objective of this paper is to examine the unsteady MHD free convection with heat and mass transfer flow of dusty fluid past an impulsive vertical plate in presence of thermal radiation. Both the fluid viscosity and thermal conductivity are assumed to be vary as an inverse linear function of temperature. Effect of viscous dissipation is consideration in the energy equation. Resultant equations are solved numerically by applying the finite difference method. To illustrate the influence of various physical parameters involved in the problem on the velocity, temperature and species concentration of fluid and dust particles are presented graphically. Numerical results of Skin friction, Nusselt number and Sherwood number are also completed and presented in tabular form.
