| Abstract: | The paper deals with theoretical and experimental aspects of lumped capacitance model (LCM) application for the study of heat transport in different materials. Patented construction of the measuring chamber together with special software the fundamental features of which are presented here allows evaluating thermal conductivity k, specific heat capacity cp and thermal diffusivity α. Obtained results are in relatively very good agreement with those obtained from independent measurement or table values. |
