Abstract

The results of mathematical simulation of thermal conditions of a typical element of radio electronics or electronic engineering are reported. The element presents a gas-filled cavity surrounded by finitely thick solid walls and containing a local heat source. It is shown that a change in the emission intensity of the heat source in the initial time stage destabilizes the thermal plume, and a slight external perturbation has a profound effect upon the hydrodynamics and heat transfer in the system. It is established that the possibility exists of controlling the gas flow velocity and the distribution of temperatures in the cavity by choosing the optimal material for the solid walls and the thermal conditions at the outer contour of the decision region.
