Abstract

Abstract

In this study the magnetohydrodynamics(MHD)natural convection heat transfer with Joule and viscous heating effects inside iso-flux porous media filled inclined rectangular enclosures was studied numerically.An iso-heat flux was applied for heating and cooling the two opposing walls of the enclosure while the other walls were adiabatic.The Forchheimer extension of Darcy-Oberbeck-Boussinesq and energy equations were transformed into dimensionless form using a set of suitable variables than solved using a finite difference scheme.The governing parameters are:the magnetic influence number,the modified Rayleigh number,the inclination angle,and the aspect ratio of the enclosure.The results show that the viscous and Joule heating effects decrease heat transfer rates.
