Thermal Radiation on Mixed Convective Flow in a Porous Cavity: Numerical Simulation

[摘要] In this paper, the influence of mixed convection in a porous square enclosure under the effect of radiation is numerically examined. The top and bottom walls are maintained at uniform temperature θ c while some portion of the vertical walls is partially heated with temperature θ h and rest of the vertical walls are thermally insulated, with θ h > θ c . The non-dimensional governing equations are solved by MAC (Marker and Cell) method. The effect of various parameters (thermal Grashof number, Darcy number, Prandtl number, Reynolds number) on flow patterns and heat transfer has been presented.
