Περίληψη:Title screen
A mathematical modeling of conjugate heat transfer in a semi-open rectangular cavity filled with air and semi-restricted by solid heat-conducting walls of finite thickness is performed under conditions of radiant energy supply in a mixed convection mode. According to the results of numerical modeling, differential (fields of temperature and stream function) and integral (average Nusselt numbers) characteristics of heat exchange have been obtained in a wide range of governing parameters (104 ? Ra ? 106, 300 ? Re ? 700). Based on the analysis of temperature and stream functions fields, it was established that the conjugate heat transfer process under study had a significantly unsteady nature. Scale influence of lifting force increasing on isolines of temperature and stream function formation in the air cavity is shown. It was found that an increase in the Rayleigh number leads to a rise in the average Nusselt number in a mixed convection mode..
