This study is to determine the thermal properties of a paraffin/red brick composite to determine its viability as a form-stable phase change material. Extended graphite was also added to the composite to improve its thermal conductivity. The thermal conductivity for this material was measured using a transient plane source (TPS) method. By adding the paraffin, the thermal conductivity of the composite increase, also by adding extended graphite the thermal ...
The thermal properties of oil palm shell (OPS) are investigated to determine if it could be used as a lightweight aggregate for a concrete mixture. The thermal conductivity, diffusivity, and specific heat were all tested through a transient plane source (TPS) method. The thermal conductivity and diffusivity both increased as the volume fraction of OPS increased. This is because OPS is very porous which gives it an inherently low thermal ...
This article investigates how the thermal conductivity of a resorcinol-formaldehyde aerogels varies with increasing resorcinol (R) to water (W) ratios. The thermal conductivity was measured using a transient plane source (TPS) method. As the R:W increases so does the thermal conductivity, this is because there is more conductive solids present to transfer more energy....
The high temperature fire resistance of vanadium is not well documented, so its properties are usually approximated to the same as conventional structural steels. The goal of this study is to determine the properties that influence the fire resistance of structural steel, thermal conductivity, specific heat and thermal elongation. Thermal conductivity and specific heat were both determined through a transient plane source (TPS) method. Vanadium and A36 steel were both ...
The purpose of this study is to demonstrate the ability of a transient plane source (TPS) method to measure thermal conductivity, thermal diffusivity, and volumetric heat capacity. Four samples were tested standard steel, linear low-density polyethylene (LLDPE), LLDPE with 5 wt% graphite composite, and LLDPE with 15 wt% graphite composite. Steel had the highest thermal conductivity because steel has more free electrons then the other materials. LLDPE had a lower thermal conductivity ...
