Forced Convection in a Heterogeneous Parallel-Plate Channel: Use of the Brinkman-Forchheimer Flow Model
A. V. Kuznetsov
This paper presents a new boundary layer type solution of a problem of forced convection in a heterogeneous channel filled with two different layers of isotropic porous media. The Brinkman-Forchheimer-extended Darcy equation is utilized to describe the fluid flow in porous layers. Three boundary layers are identified in the channel: a boundary layer at the solid wall and two boundary layers at the interface between the porous media. The dependence of the velocity and temperature profiles and the Nusselt number on values of the Darcy number in different parts of the channel and on values of the Forchheimer coeffcients is investigated.
