Abstract
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 fields and stream functions) and integral (Nusselt numbers) heat transfer characteristics have been obtained. It has been shown that the radiant flux distribution influences the heat transfer intensity.
