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 ...
Copper powder was used a filler and added to a polyamide matrix in order to generate copper reinforced polyamide composites. The copper powder came in three different forms: short fibers, plates and spheres. The short fibers were added to the polyamide matrix at a vol.% up to 30, and the plates and spheres up to 60 vol.%. Thermal conductivity was measured and it was found that at filler amounts below 10 vol.% the ...
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 ...
