Abstract

The prime findings of a numerical investigation into conduction-convection-radiation heat transfer from an electronic gadget, modeled as a discretely and non-identically heated L-corner, are elucidated. In total, four heaters of different heights are assumed to be embedded in the gadget [three in the left and one in the bottom wall]. The partial differential equations describing temperature variation in the computational domain are deduced by balancing the heat generated with that transported by three possible modes of heat transfer. Air [assumed to be radiatively non-participating] is the medium used for cooling the gadget. Finite difference method is used to enable the governing equations acquire an algebraic form. Consequent equations are solved through the Gauss-Seidel algorithm. Full relaxation is imposed to update the local temperature as it gets iterated, and the iterations are made to halt when the maximum residue goes below 10−8. The effects of all the pertinent independent properties on different prominent results are rigorously probed into. The explicit role enacted by radiation in the work taken up here has been underlined through certain precisely executed results.
