The authors make some kind of modification to the TPS technique and then call it the advantageous TPS (ATPS) technique, which apparently has an improved experimental arrangement. It is also claimed that there is more automation in data acquisition, better accuracy and easier calculations. Fused quartz, low carbon steel and silver chloride crystals are studied with the ATPS technique, with the use of liquid nitrogen to cool the silver chloride ...
Oil-palm fiber reinforced phenolformaldehyde composites were prepared and then tested for their thermal properties. Thermal conductivity and diffusivity were measured using the transient plane source (TPS) technique. The composites were then treated using different methods (alkali, silane and acetic acid treatments) and the thermal conductivity and diffusivity were measured again to see how the treatment affected the thermal properties of the composite. It was found that thermal conductivity increased varying ...
The researchers used the transient plane source (TPS) technique for the measurement of a variety of solid and liquid reference materials in order to assess the capability of the TPS technique. Specifically probe size and contact were studied to see how they affected the transient measurements. In addition, the influence of natural convection on liquid samples was studied. While multiple thermal properties can be measured using the TPS technique, thermal ...
Using a combination of transient plane source (TPS) technique and slug calorimetry, 4 commercially available fire resistive materials (FRMs) are studied from room temperature to 1000°C. The materials studied in this report are two gypsum-based and two calcium-silicate based materials. These materials are heterogeneous and thus when heated to elevated temperatures, the microstructure of the materials may be compromised and various reactions and phase changes may take place over the course ...
Varying weight percentages of pineapple leaf fiber were added to phenolformaldehyde (PF) in order to generate a composite material. Using the transient plane source (TPS) technique, the thermal conductivities of the varying weight percentage composites were studied. It was found that increasing weight % pineapple leaf fiber resulted in decreasing thermal conductivity and diffusivity of the composites. The experimental results are compared to results produced by two models (the Rayleigh-Maxwell and ...
