Abstract

Mathematical simulation of the nonstationary regimes of heatandmass transfer in a ventilated rectangular cavity with heatconducting walls of finite thickness in the presence of a heatgenerating element of constant temperature has been carried out with account for the radiative heat transfer in the Rosseland approximation As mechanisms of energy transfer in this cavity the combined convection and the thermal radiation in the gas space of the cavity and the heat conduction in the elements of its fencing solid shell were considered The mathematical model formulated in the dimensionless stream function–vorticity vector–temperature–concentration variables was realized numerically with the use of the finitedifference method The streamline temperaturefield and concentration distributions reflecting the influence of the Rayleigh number Ra = 104 105 106 the nonstationarity 0  τ ≤ 1000 and the optical thickness of the medium τλ = 50 100 200 on the regimes of the gas flow and the heatandmass transfer in the cavity have been obtained
