Abstract
Mixed convection in a porous medium from a vertical plate with variabl e wall temperature is investigated. The entire mixed convection regime is divided into two regions and two sets of transformations are used. The first region is for the forced convection dominated regime (FCDR) and the other one is for the natural convection dominated regime (NCD R). The dimensionless parameter K'U-infinity/nu is found to characteri ze the effect of inertia resistance in the first region and the dimens ionless parameter (K'U-infinity/nu)(Ra-x/Pe(x)) is found to characteri ze the effect of inertia resistance in the second region. The solution of the first region is carried out from xi(f) = 0.0 to xi(f) = 1.0, a nd the solution of the second region is carried out from xi(n) = 0.0 t o xi(n) = 1.0. Velocity and temperature profiles are calculated at dif ferent values of the governing parameters. Local Nusslet number variat ion for the entire mixed convection regime is also calculated and pres ented.
