A method for determining simultaneously the temperature dependent thermal conductivity and volume heat capacity
Abstract
The temperature curves at two faces of a symmetrically heated sample are obtained experimentally, and the temperatures under these conditions are calculated from a heat equation, using a priori approximate values of the thermophysical characteristics. A procedure for minimizing the discrepancy between the experimental and analytical results is proposed, and the thermal conductivity and volume heat capacity that correspond to the calculated temperatures that are closest to the experimental ones are taken as the best approximations to the actual heat conductivity and volume heat capacity of the sample studied.
