COMPUTER MODELING AND ANALYSIS OF THERMAL INFRARED SYSTEMS uniform irradiation FLAT SURFACES

A.А. Zavaliy

Examined the systems of infrared heating, containing one or two sources of radiation, specular reflecting surfaces and one or two flat surfaces of irradiation. With the use of optical-geometric models are constructed surface mirroring to ensure uniform heating of the surface exposure. Based on the numerical solution of integral equations of energy transfer radiation in an optically transparent medium developed models of the thermal analysis of state of the systems. The analysis of the thermal state of the infra-red heating systems has shown that a simple geometric-optical models allow us to create a closed system of infrared heat themes with mirror reflective surfaces that provide substantially the alignment distribution of the radiation flux on the surface of the irradiation. To increase the uniformity of exposure is possible to use a consistent correction of geometric shapes mirror reflective element system, which consists in changing the position of teaching-stkov specular surfaces and thermal analysis of the modified system.

Key words: thermal modelling and infrared heating, mirror reflecting surface.
