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 ...
Multiwalled carbon nanotubes (MWCNT) have applications in the aeronautic industry. This study examined how the concentration of MWCNT affects the electrical and thermal conductivities of nanocomposites. A thermal analyzer (TPS) measured the thermal properties of the nanocomposites using the transient plane source (TPS) technique. Results showed that thermal conductivity of the samples increased with MWCNT concentration and temperature, but the phenoxy-MWCNT nanocomposites had higher thermal properties than the PES-MWCNT nanocomposites....
Phase change materials have supercooling characteristics that would benefit long-term latent heat thermal energy storage. This paper studied the physical and chemical properties associated with the growth rate of crystallization in disodium hydrogenphosphate dodecahydrate (DHD) as a function of a degree of supercooling. The transient plane source (TPS) technique was used to measure the thermal conductivity of the DHD samples. Results of the thermal conductivity test showed that the solid ...
Aspects of hydrogen distribution systems need improvement for their applications in fuel cell vehicles. In this paper, chemical and physical characteristics of the H2 storage material, sodium aluminum hydride (SAH), were examined after the samples were compacted and Expanded Natural Graphite (ENG) worms were added. A Thermal Constants Analyzer (TPS) measured the thermal conductivity of the SAH pellets with (ENG) worms using the Transient Plane Source (TPS) method. Results showed ...
Understanding the thermal properties of soils is important for applications in agronomy and engineering. The aim of this study was to examine the thermal properties of volcanically-derived Chilean soils using the Transient Plane Source (TPS) method. Results showed that thermal conductivity decreased with water content and with increasing amounts of organic carbon. Alternatively, soils with increased concentrations of crystalline compounds exhibited higher thermal conductivities. Results of this paper conclude that ...
