Features of Heat Exchange Processes under the Influence of Radiation

Radiation is one of the factors of external influence on the structural elements of the aircraft that perform high-speed flight in dense layers of the atmosphere and the units of traction power plants. It occurs during the combustion of large masses of combustible substances, and the artificial sources of radiation in the form of incandescent lamps and based on the principles of electric discharge in gases are widely used in technical devices. The article presents the main provisions and relations of the theory of heat-radiation exchange and considers the features of the interaction of radiation with materials, including those that exhibit partial transparency in relation to radiation and the features of heat exchange processes associated with this factor. The article also focuses on the use of radiation sources in thermal testing of structures.
