APPLICATION OF SOLUTIONS OF INVERSE HEAT CONDUCTION PROBLEMS FOR RESEARCH OF MATERIALS THERMAL CONDUCTIVITY IN WIDE RANGE OF ITS VALUES AND TEMPERATURES

The technology for research of thermal conductivity of different materials is offered. It consists of experimental determination of one-dimensional temperature fields in heat-receivers (samples with thermal sensors) from a researched materials and use of these fields for the solving of inverse problems of heat conductivity. Investigation of materials with low (0.6 Wm⁻¹K⁻¹) and high (160 Wm⁻¹K⁻¹) thermal conductivity by the application of offered technology to research an influence of different factors on temperature dependence of thermal conductivity is considered.
