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 ...
The authors used the transient plane source technique for measuring the thermal conductivity, diffusivity and specific heat of highly porous materials. This paper helped to demonstrate that the newly developed TPS technique wasn't just for the measurement of isotropic bulk materials. Different samples of wood composites were analyzed. Once measurements were obtained using the TPS method, they were compared to results obtained theoretically using Verma's model for prediction of thermal ...
Paper that presents a slightly modified version of the early transient plane source technique which allowed the easier measurement of thermal transport properties of solid materials. A series of building materials were tested spanning thermally conductive to thermally insulating materials including extruded polystyrene, polymethyl methacrylate (PMMA), stainless steel and aluminum. This modified method allow the measurement of thermal conductivity values from 0.02 W/mK to 200 W/mK....
The authors highlight different methods of studying the purity, composition, and structural changes of polymeric and glass materials. These methods include the use of differential scanning calorimetry (DSC) and the transient plane source (TPS) technique. The quality of the TPS Technique is outlined and the authors praise the high quality of the machine. In addition to this, thermal analysis is carried out on some polymeric composites (cis-polyisoprene (CPI)/trans-polyisoprene (TPI) ...
A series of compacted Bi0.5Sb1.5Te3 nanoplatelets are synthesized using hydrothermal methods, followed by cold pressing and sintering at temperatures between 300°C and 380°C. A variety of thermal, mechanical and electrical analyses are then performed on the synthesized nanoplatelets including: TPS technique for thermal conductivity, SEM/TEM/AFM to elucidate the mechanical and physical properties of the nanoplatelets, and the Oxford closed cycle cooler cryostat for measurement of electrical ...
