This article explains the theory behind the Transient Plane Source (TPS) technique. The method measures the thermal conductivity and diffusivity of materials (solids, liquids, gels, etc.), in a rapid, non-invasive and highly accurate manner. The TPS method is a great technique to be used for thermal characterization as it has a wider thermal conductivity range (0.005 – 500 W/mK) and an easy set-up. The sensor serves as both a temperature gauge and ...
This research article proposes the use of a thermal constants analyzer to measure thermal properties of relatively thin samples. Five different metallic samples containing copper, aluminum and brass were used to test the accuracy of the new and improved method. Previously, this method has been used to test the thermal properties of thin metallic sheets, however with the new and improved method, it is possible to measure samples with thicknesses ...
Thermal conductivity testing was done on nitrogenated ultrananocrystalline diamond films on silicon. Temperature dependence on thermal conductivity was measured using these two techniques. A decrease in thermal conductivity was observed with the introduction of nitrogen addition. It was observed that MCD had the highest thermal conductivity followed by UNCD at 25% nitrogen and UNCD at 0% nitrogen....
