Transient non-Darcy mixed convection along a vertical surface in porous medium with suction or injection

Transient non-Darcy mixed convection from a semi-infinite, isothermal vertical plate embedded in a homogeneous porous medium, in the presence of surface suction or injection has been numerically investigated. Forchheimer extension is considered in the flow equations. Appropriate transformations are employed to transform the governing partial differential equations to a non-similar form. The transformed equations have been solved numerically using an implicit finite difference scheme. Numerical results illustrating the effects of all involved parameters on the transient velocity and temperature profiles, the local Nusselt number and the friction coefficient are presented and discussed.
