Mixed Convection Heat Transfer from a Vertical Plate Embedded in a Bidisperse Porous Medium

This work studies the mixed convection heat transfer from a vertical plate in bidisperse porous media with constant wall temperature. The two-velocity two-temperature model is used to derive the governing equations. The effects of the mixed convection parameter, the inter-phase heat transfer parameter, the modified thermal conductivity ratio, and the permeability ratio on the heat transfer and flow characteristics have been studied. Results show that an increase in the mixed convection parameter, the modified thermal conductivity ratio, or the permeability ratio can effectively enhance the mixed convection heat transfer of the vertical plate in a bidisperse porous medium. Moreover, the thermal non-equilibrium effects between the f-phase and the p-phase becomes significant as the inter-phase heat transfer parameter or the mixed convection parameter is small.
