Experimental Setup for Measuring Thermal Conductivity of Liquids, Gases, and Solids by the Pulse Heating Method

The article is devoted to methods of studying thermal conductivity and, in particular, to the pulse heating method. The classification of methods for studying thermal conductivity and their advantages and disadvantages are described. The article provides generalized information about the probes used in experimental setups of the pulse heating method as well as a description of the probe used in the implemented setup. Experimental thermograms with an analysis of the factors influencing the result, as well as options for assessing their contribution to the overall measurement result, are presented. The results of testing the installation and comparison of the obtained values of thermal conductivity coefficients with standard values presented in the literature are presented.
