ABSTRACT

In this dissertation, the problems of Magnetohydrodynamic unsteady free convection flow past vertical porous plates with suction and oscillating boundaries are studied. The linear and nonlinear partial differential equations governing the flow problems and boundary conditions were transformed into dimensionless form, and the perturbation techniques applied in getting analytical solutions for the velocity, temperature, the skin friction coefficient and Nusselt number. It was observed that an increase in the values of thermal Grashof number, Eckert number and heat source increases velocity profile, while an increase in Darcy term retards the velocity profile. An increase in heat source and Grashof number, also increases the Heat transfer coefficient. The effects of various parameters on the flow fields have been presented with the help of graphs and tables.
