The authors describe the dynamic plane source, a transient method of measuring the thermal conductivity, diffusivity and specific heat of a sample. This method uses a sensor, and relies on the premise of an adiabatic system. Using this method, the thermal properties of cast iron, pure iron and stainless steel are measured. The experimentally obtained values match with the literature values quite closely....
The authors report on the use of the newly developed transient plane source (TPS) technique for the measurement of thermal conductivity and thermal diffusivity of insulators, fluids and metals. The paper describes the theory and experimental setup used, including the sensor and how it works. The experimentally obtained values were compared to literature values and showed good agreement....
Using the transient plane source (TPS) method, the thermal conductivities of a series of crosslinked closed-cell polyethylene foams were measured. The experimental values obtained were compared to measurements made by a steady-state method (heat-flow meter). Through the use of the TPS technique, it was possible to observe how physical characteristics such as cell size, density and carbon black content affected the overall thermal conductivity. The authors found that the trends ...
Using TPS sensors, the thermal conductivity, diffusivity and specific heat of thin samples of metallic materials have been measured. The article highlights that the TPS method can accurately predict the thermal properties of small sample sizes. In addition, specific heat capacity can be measured using slightly longer experiments. The measured properties agree with their literature values, and have high precision....
For the prediction of thermal conductivity using theoretical models of a composite or mixture of components, the thermal conductivities of the individual components must be known. In this study, the needle probe method was used to measure the thermal conductivity of a mixture of powder and fluid, and using the law of mixtures (Hashin-Shtrikman bounds) the thermal conductivity of the solid phase is estimated. A much simpler method exists though ...
