ANALYSIS OF FREE-CONVECTIVE REGIMES OF HEAT TRANSFER IN CLOSED DOMAIN WITH WORK OF INFRARED EMITTERS
Are the results of numerical studies of heat transfer in the regime of free convection in the closed rectangular region, heated by infrared emitter. Solved the system of Navier- Stokes equations in the approximation of Boussinesq, equation of energy for the gas, which is been located inside the locked outline, and the equations of thermal conductivity for the enclosing vertical and horizontal walls. Is carried out the comparative analysis of several typical free-convective regimes of heat transfer in the region in question. The essential transiency of the analyzed heat transfer process is established. Are isolated the special features of the formation of temperature fields with work of infrared emitters.
