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.
