T1 Unsteady Free Convection in a Fluid Past a Vertical Plate Immersed in a Porous Medium JF International Journal of Fluid Mechanics Research JO FMR YR 2008 FD 2008-12-02 VO 35 IS 5 SP 434 OP 444 AB In this work we examine the problem of unsteady free convection from a vertical flat plate to a fluid-saturated porous medium. The flow field is modeled by Darcy−Brinkman−Forchheimer model. Boundary layer and Boussinesq approximations have been incorporated. Numerical calculations are carried out for the various parameters entering into the problem using the finite difference method. It is found that as time approaches infinity, the values of friction factor and heat transfer coefficient approach the steady-state values.
