In this study, the effective thermal conductivity of compacted granular beds is investigated. Thermal conductivity was measured using the transient plane source technique. Granular beds of varying particle sizes were analyzed using various sensor sizes. Results found the effective thermal conductivity to increase with increasing granule size. Smaller sensor sizes were also found to give a larger effective thermal conductivity....
The goal of this study was to determine how adding CdS nanoparticles to two polymer blends (PS/PVC and PS/PMMA) affects their thermal conductivities. Also, the effect of increasing the wt% of both PVC and PMMA in their respective blends was investigated. The thermal conductivity of the samples was determined through a transient plane method. The thermal conductivity of both polymer blends increased with the addition of CdS nanoparticles. ...
This study aimed to enhance the thermal and mechanical properties of polyethylene (PE)/boron nitride (BN) composites by manipulating the BN concentrations in the matrix and by applying shear fields in laminating-multiplying elements (LMEs). A thermal constants analyzer measured the thermal conductivity of the PE/BN composites using the transient plane source (TPS) method. Results showed that the thermal conductivity of the composites increased with BN concentration. As well, the ...
Synthetic polymers in starch-based polymer formulations improve the thermal and mechanical properties of the compounds. The purpose of this study was to develop and analyze foams containing ethylene-vinyl acetate (EVA) and varying concentrations of corn starch. A Thermal Constants Analyser measured the thermal conductivity of the EVA/starch samples using the transient plane source (TPS) method. Results showed that the thermal conductivity of the blends increased with starch content. The ...
Polyoxymethylene (POM) is a resistant polymer with wide applications in aerospace, automotives, and biomedicine. However, it falls short when used in the manufacturing of sliding parts. In this study, copper particles and polytetrafluoroethylene (PTFE) powder were incorporated into POM to improve the thermal conductivity of the polymer composite while reducing the friction coefficient. A thermal analyzer was used to measure the thermal conductivity of POM composites using the transient plane ...
