Abstract Share this page

Mixed convection in a porous medium from a vertical plate with variable 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 (NCDR). The dimensionless parameterK′U∞/ν is found to characterize the effect of inertia resistance in the first region and the dimensionless parameter (K′U∞/ν (Rax/Pex) is found to characterize the effect of inertia resistance in the second region. The solution of the first region is carried out from ξf=0.0 to ξf=1.0, and the solution of the second region is carried out from ξn=0.0 to ξn=1.0. Velocity and temperature profiles are calculated at different values of the governing parameters. Local Nusslet number variation for the entire mixed convection regime is also calculated and presented.
