Abstract
A new method is proposed, for the determination of thermal radiation properties, which allows prompt and exact determination of optical characteristics of the surfaces of bodies taking part in radiative heat exchange, as well as of angular coefficients of radiation, surface density of the resultant radiant flow and surface intensity of heat accumulation. The method is based on an analytical treatment of the curve obtained from a heated sample. When optical characteristics of materials are determined, the geometry of the radiative system is taken from the values of angular coefficients of radiation known exactly beforehand. This provides a reliable criterion for estimating the correctness of an experimental installation and the accuracy of results obtained in experiments carried out in accordance with developed methods.
