A numerical study on the theoretical accuracy of film thermal conductivity using transient plane source method 

Currently, there is no research into the accuracy of the transient plane source (TPS) method for measuring the thermal conductivity of thin films. The purpose of this study is to use numerical simulation to determine the accuracy of thermal conductivity measurements of thin films, with the TPS method. The values produced from the TPS method closely resembled those of the numerical simulation. The deviations from the numerical model were caused ...

Determining thermal physical properties of pyrolyzing New Zealand medium density fibreboard (MDF) 

Understanding the pyrolysis model for medium density fibreboard (MDF) is important for infrastructure fire safety. The purpose of this study was to determine the thermophysical properties of charred and uncharred MDF. The thermal conductivity of these inhomogeneous fibreboards was measured using a Thermal Constants Analyser in conjunction with the transient plane source (TPS) technique. Results showed that the experimental results were in good agreement with literature values, and specifically, the ...

Combination of Transient Plane Source and Slug Calorimeter Measurements to Estimate the Thermal Properties of Fire Resistive Materials

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 ...


Direct measurement of through-plane thermal conductivity of partially saturated fuel cell diffusion media

This thesis looked at the relationship between thermal conductivity and compression and saturation in three different fuel cell diffusion media (DM). The stress-strain relationship of the materials was investigated using an optical microscope, and thermal conductivity was measured by a thermal constants analyzer. A theoretical model of the maximum through-plane thermal conductivity was developed as a function of compression and saturation....


Ultrathin BN nanosheets with zigzag edge: one-step chemical synthesis, applications in wastewater treatment and preparation of highly thermal-conductive BN-polymer composites

Ultrathin boron nitride nanosheets (BNNSs) were prepared at 300°C by a new variable-pressure one-step synthesis. An increase in pressure during the synthesis results in a decreased thickness for the nanosheets, which were all triangular in shape with zig-zag edges. The synthesized nanosheets exhibit high adsorption capacities for the organic dye methylene blue (MB). In addition to these properties, the BN nanosheets can be used as excellent thermal-conducting additives in BN-polymer ...
