Abstract

Abstract: The effect of two fundamental arrangements of discrete heaters on the combined thermal radiation and natural convection in a square enclosure is investigated numerically. The heaters are placed either side by side or one above the other within the air filled enclosure. The nonlinear conservation equations for the resulting flow were solved by a finite volume based computational method. The steady state results which provide qualitative information on the nature of fluid flow are discussed. The present results are of use in some geometrical considerations for the optimal design of air cooled electronics.
