COMPUTATIONAL MODELING OF CONJUGATE HEAT TRANSFER IN A CLOSED RECTANGULAR DOMAIN UNDER THE CONDITIONS OF RADIANT HEAT SUPPLY TO THE HORIZONTAL AND VERTICAL SURFACES OF ENCLOSURE STRUCTURES

We have carried out computational modeling of nonstationary conductive-convective heat transfer in a closed rectangular domain in a conjugate formulation with a local heat source (a gas infrared radiator). Four variants of possible description of the radiant energy distribution over the inner surfaces of enclosures have been considered. As a result of the computational modeling, differential (temperature fi elds and stream functions) and integral (Nusselt numbers) heat transfer characteristics have been obtained. It has been shown that the radiant fl ux distribution infl uences the heat transfer intensity.
