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 ...
Using the transient plane source (TPS) method, the thermal conductivities of a series of magnesium integral foams have been measured experimentally. The main factor contributing to the thermal conductivity of the magnesium foams is the bulk density. In addition to using the TPS technique, micro-computed tomography (µCT) was used to explain any deviations from expected thermal conductivity....
A modification was made to the transient plane source (TPS) technique for the measurement of thermal transport properties at low temperatures (as low as 80 K). This altered TPS technique was then used to measure the properties of known samples in the form of fused silica, carbon steel and halide crystals. Data were obtained from room temperature down to 80 K. The newly modified method gave experimental results that agreed well with ...
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....
