Abstract

A detailed numerical analysis of complex heat transfer (turbulent natural convection, conduction and surface thermal radiation) in a rectangular enclosure with a heat source has been carried out. The finite difference method for the solution of the governing equations using the dimensionless stream function, vorticity and temperature variables has been utilized. The effects of Rayleigh number in a range from 108 to 1011, thermal conductivity ratio in a wide range from 10 to 1000, as well as internal surface emissivity 0 ≤ ϵ < 1 on the fluid flow and heat transfer have been extensively explored. Detailed results including temperature fields, flow profiles, and average Nusselt numbers have been presented. In this investigation we have tried to study the main regularities of heat and mass transfer in the considered domain.
