Natural Convection in a Tilted Square Enclosure Having Heat Generating Solid Body and with Various Thermal Boundaries

摘要

Steady laminar natural convection around a heat conducting and generating solid body inside a two-dimensional tilted square enclosure with different thermal boundaries are investigated numerically. The mathematical model is governed by the coupled equation of mass, momentum and energy. These equations are solved using SIMPLE algorithm by means of the finite-volume method together with under-relaxation technique. Effect of angle of inclination of enclosure, aspect ratio of solid-enclosure, temperature difference ratio of solid-fluid and the thermal conductivity ratio of solid-fluid are analyzed. The fluid circulation and the corresponding heat transport inside the enclosure are represented in terms of streamlines and isotherms respectively.
