An investigation into the thermal properties of infiltrated and non-infiltrated copper windings was performed. Of particular interest was the radial thermal conductivity. The thermal conductivity measurements were performed, and the anisotropic testing module. The results of the testing were then compared to calculated values obtained by finite element modelling, as well as by a homogenization relation proposed by Hashin and Shtrikman. It was determined that there was a significant difference ...
This thesis presents a literature review of techniques for measuring the thermal conductivity of engineering materials. In addition to this, the cylindrical specimen apparatus developed at Arizona State University was improved upon, and this method was used to measure the thermal conductivity of five different materials. The results of this testing were compared with results obtained using the guarded hot-plate method, and the results were in good agreement with each ...
Graphite nano-platelets (GnPs) were dispersed in polyethylene glycol (PEG)/polymethyl methacrylate (PMMA) to form a PEG/PMMA/GnPs composite organic form-stable phase change material. The effects of the incorporation of the GnPs on the morphological, structural, thermal, and electrical properties of the composite were then assessed. The experimental results indicated that the incorporation of the GnPs into the polymer increased the thermal and electrical conductivities, and it was concluded that ...
Si-SiC composite foams were prepared using tannin-based foams as templates. The foams were prepared by four different methods for the determination of which method would best produce a foam with a pore size under 200 µm. The foam samples were characterized by SEM, XRD, and Raman spectroscopy, and the thermal conductivity of one of the foams was investigated by the transient plane source method. It was found that direct infiltration of ...
The thermal properties of engineered bamboo products were investigated as these products show promise for use as building materials due to their improved mechanical properties over traditional timber building materials. It was determined that the thermal conductivity was lower for the bamboo materials than for timber, which indicates that these materials could potentially be used in the construction of energy efficient buildings....
