Abstract
Numerical analysis of 3D regimes of convection-radiation heat transfer in cubic enclosure with two isothermal faces and adiabatic walls is performed. The mathematical model is constructed in dimensionless variables “vector potential-vorticity vector-temperature” in the Boussinesq approximation and with regard to diathermal medium filling the enclosure. 3D temperature and velocity fields, medium motion trajectories in a wide range of key parameters are obtained. Correlations for the integral heat exchange coefficient as a function of the key process characteristics are found.
