Abstract

Conjugated natural convection and conduction in a square cavity containing a POROUS MEDIUM with a SOLID BODY subjected to a uniform energy generation per unit volume is studied numerically in this paper. The vertical walls of the cavity are assumed to have constant temperatures (Th and Tc) and the horizontal walls to be adiabatic. The effective parameters in this case are Ra and lsb which appear in the nondimensionalized equations. Ra is a function of temperature difference between hot and cold walls, and lsb is a parameter that depends on the energy generation in the POROUS MEDIUM. Nondimensionalized governing equations in both cases are obtained based on the darcy model; a control volume approach is used for solving these equations. The effect of the variation of two parameters, Ra and lsb, on the heat transfer rate, fluid flow and isotherms are investigated. The results show that the maximum temperature decreases as Ra increases or lsb decreases.
