Abstract
Heat transfer under the influence of radiation and viscous dissipation in a square cavity filled with saturated porous medium is analysed. The flow is assumed to follow Darcy law. The governing equations are non-dimensionalised and solved numerically using finite element method. Left vertical surface of the square cavity is maintained at isothermal temperature Th and right vertical surface at Tc. Results are presented in terms of Nusselt number at hot and cold wall of the cavity for various values of viscous dissipation parameter and radiation parameter. It is seen that the average Nusselt number at hot as well as cold wall increases with increase in radiation parameter.
