The mathematical model for a transient plane source (TPS) is based on a number of concentric ring sources with an infinitely small gap between sample and sensor (strips model). The purpose of this article is to create a model that accounts for the size of the sensor, three models were tested the disk, circles, and rings. The circles model gave almost exactly the same values for thermal conductivity as the ...
The purpose of this study was to analyze the thermal properties of metal hydride for its application in hydrogen storage systems. The thermal properties of metal hydride were measured using the Thermal Property Analyzer based on the transient plane source (TPS) method. To verify the accuracy of the TPS method, the thermal properties of stainless steel pellets were measured prior to the metal hydride samples. Unfortunately, the thermal behavior of ...
Diamond is an extremely conductive material that would be ideal for dissipating heat in microelectronics if it were not for its high price tag. In this study, cost effective copper- and chromium-diamond composites (uncoated (Cu/D), Cu-coated (Cu/CuD), and Cr-coated (Cu/CrD)) were produced to determine their potential use in heat sink applications. A Thermal Constant Analyzer measured the thermal conductivity of the matrix and composite samples using the ...
The transient plane source (TPS) method is a popular technique that is used to measure the thermal properties of solids. The TPS method is widely used because it can test a variety of materials, it is easy to set up, and measurements are non-invasive. A downside of the TPS method is that it requires two homogenous samples, unlike invasive contact-probe techniques. This study proposes the idea of a “stamp sensor”, ...
The transient plane source (TPS) technique has a wide range of applications because of its capability to test solids, liquids, powders, and anisotropic materials over a range of sizes. Thermal properties of thin films and coatings can also be characterized using the TPS method if the samples are placed between the sensor and a bulk background. To minimize errors with the TPS method, use identical materials on each side of ...
