A boundary layer solution of a forced convection problem in a composite channel partly filled with a porous medium
Forced convection in a composite region part of which is occupied by a clear fluid and part by a fluid saturated porous medium has recently attracted considerable attention and became a subject for numerous investigations. This interest is due to many important thermal engineering applications related to this problem. Solid matrix heat exchangers, the use of porous materials for heat transfer enhancement, fault zones in geothermal systems and solidification of binary alloys are few to mention in this respect. In this paper a problem of fully developed forced convection in a parallel-plate channel partly filled with a homogeneous porous material is considered. The flow in the porous material is described by nonlinear Brinkman-Forchheimer-extended Darcy equation. Utilizing the boundary layer approach, analytical solutions for the flow velocity, the temperature distribution, as well as for the Nusselt number are obtained.
