MIXED CONVECTION OF A COMPOSITE POROUS MEDIUM IN A VERTICAL CHANNEL WITH ASYMMETRIC WALL HEATING CONDITIONS

[[abstract]]The fully developed laminar mixed convection flow of a composite porous medium in a vertical channel is presented. The flow is modeled using a Brinkman model. The viscous and Darcy dissipation terms are also included in the energy equation. Three types of thermal boundary conditions, such as isothermal-isothermal, isoflux-isothermal, and isothermal-isoflux, for the left-right walls of the channel are presented. The coupled nonlinear governing equations are solved using a regular perturbation method. The effects of various parameters on the flow, such as porous parameter, ratio of Grashof number to Reynolds number, width ratio, viscosity ratio, and thermal conductivity ratio, are discussed.[[note]]SC
