Experimental determination of the temperature in a small neighborhood of the gas infrared sources

The results of the experiments carried out are the logical justification for the development of the heat transfer models in the air-filled enclosed areas which are determined by the walls of finite thickness and under conditions of the gas infrared sources operation. It was found that the air convection processes play an important role in formation of the thermal regimes of the areas heated by the radioactive flux coming from the upper boundary of such areas despite the low thermal conductivity of the gas
