Выдержка

A numerical analysis of turbulent regimes of the natural convection in a closed rectangular region with heat-conducting walls of finite thickness was carried out in the presence of a locally concentrated heat source under the conditions of the radiative-convective heat exchange with the ambient medium on one of the external boundaries. The mathematical model was constructed on the basis of the Reynolds equations in dimensionless variables stream function - vorticity vector - temperature. Special attention was paid to the investigation of the influence of the Grashof number er 108≤Gr<1010, of the unsteadiness factor 0< τ <1000, and the thermal conductivity ratio λ2,1 = 5.7·10-4, 6.8·10-5 on both the local and integral characteristics of the problem.
