Simultaneous measurement of thermal conductivity and thermal diffusivity of rock-marbles using transient plane source (TPS) technique

Abstract

The recently developed transient plane source (TPS) technique has been employed for the simultaneous measurement of thermal conductivity and thermal diffusivity of five marble samples. In this paper we discuss briefly the theory of the transient plane source method. The source of heat also serves as a sensor of temperature increase in the sample. The measured values of the thermal conductivity and diffusivity of these samples are in close agreement with the values of other marble samples reported earlier using the transient hot strip method. A comparison of these two techniques has also been given in the light of the experimental results.
