Description
Summary:The paper presents two methods for determining the thermal and physical properties of thermal barriers, differing in the range of operating temperatures and the object of which they are an integral part. The first method is based on a non-destructive approach to determining the thermal resistance of the external fencing of buildings, providing comfortable living conditions. The second method is based on taking into account the volumetric absorption of radiation by porous materials used in high-temperature installations, and the quasi-stationary heating mode. The presence of these two factors makes it possible to determine the absorption coefficient of a material located in the field of high-temperature radiation.
