【 摘 要 】

Mathematical modeling of unsteady conjugate heat transfer in a closed rectangular area with a local heat-conducting object in a gas cavity in conditions of radiative heat supply is conducted. Fields of temperatures and stream functions, illustrating the influence of Grashof number on the character of heat transfer are formulated. The dependence of average Nusselt number from time at different Grashof numbers is given. The influence of heat-conductive object on the intensity of heat transfer in under study solution domain is shown.
