A finite-difference analysis of transient free convection flow of a dissipative fluid past an infinite vertical porous plate is presented here. Velocity, temperature, skin-friction and Nusselt number are shown graphically and the effects of different parameters on the flow field are discussed.
Transient free convection flow of an incompressible viscous fluid past a semi-infinite vertical plate has been studied by using an implicit finite-difference technique, which is always stable and convergent. The effect of the dissipation parameter ? on time to reach steady-state is studied. It is observed that time required to reach steady-state temperature increases with the increasing Prandtl number of fluid. Also there is a rise in the average skin-friction and a fall in the average Nusselt number due to greater viscous dissipative heat.
