Abstract
The thermal conductivity of such materials as metal, grease and rubber can be evaluated by setting them between two reference rods whose thermal conductivity is known. In this measurement, not only the contact interface temperature between the reference rod and the inserted material but also the heat transfer rate flowing through the material can be measured simultaneously. In this study, based on the physical model corresponding to the measuring system, a series of numerical analysis have been performed in order to clarify the heat flow in the system, and further the influence of the heat flow on the thermal conductivity measurement of the material has been investigated.
