Abstract

Mathematical simulation of unsteady turbulent natural convection and thermal surface radiation in a closed cavity with solid heat-conducting walls of finite thickness in the presence of a heat source of constant temperature has been carried out. The governing equations for the conservation of mass, momentum, and energy have been written using a system of partial differential equations in terms of stream function, temperature and vorticity. The boundary-value problem has been solved by the finite difference method. The effect of turbulence has been modeled using the standard  model. The effects of the surface emissivity and the nonstationary factor on the fluid flow and heat transfer have been studied. As a result of the studies, distributions of both local (isolines of the stream function and temperature) and integral (average radiative and convective Nusselt numbers) characteristics have been obtained. It has been shown that an increase in the surface emissivity leads to a modification of flow patterns and the heat transfer enhancement.
