transient natural convection between two vertical walls filled with a porous material having variable porosity

摘要

This paper analyses the effects of variable porosity and inertial force on free convective flow between two vertical walls filled with a porous material. The Brinkman-Forchheimer-extended Darcy model is used to simulate the momentum transfer in the porous domain. A numerical scheme For the transient solution of the governing equations is devised to investigate the channelling effect on The velocity field due to variable porosity of the porous matrix.
