The authors have developed a numerical model for the prediction of heat transfer capabilities of protective clothing when exposed to low-level radiant heat flux in order to increase the comfort of the protective clothing used by firefighters. It was determined that the model was able to accurately predict the properties of the clothing when the results were compared to experimental observations....
Conductive carbon fillers (carbon black, carbon fiber, and synthetic graphite particles) were added to Vectra A950RX liquid crystal polymer and the axial and radial thermal conductivities were determined experimentally for each composite. The addition of Thermocarb TC-300 synthetic graphite caused the largest increase in thermal conductivity, with in-plane thermal conductivity values reaching greater than 20 W/m K which is the minimum value for use in fuel cells. Mathematical models ...
In this work, the authors tested five organic phase change materials for thermophysical properties (density, heat capacity, and thermal conductivity) in order to determine the best path to prediction (BPP) for the thermal diffusivity of organic PCMs in the liquid phase. Separate BPPs were determined for alkanes and unsaturated acids. The identified BPPs were then tested on a variety of materials and the estimated thermal diffusivity was within 15% for all ...
The authors investigate the use of two hemp-lime plasters (Chanvribat hemp-lime plaster (CHLP) and Terrachanvre hemp-lime plaster (THLP)) for their hygric and thermal properties to assess their use as building plasters. It was shown that the two-hemp lime plasters assessed were good thermal insulators and hygric regulators and so they would be a good choice for plaster to improve the hygric and thermal performances of walls so long as they ...
The thermal properties of five sandstones were measured. The sandstones were taken from the base of Khewra located in Pakistan. The thermal conductivity, thermal diffusivity, and specific heat capacity were determined using the transient plane source technique, and the porosity and density of the sandstone samples were also determined. A formula for the estimation of thermal conductivity was modified to better fit the experimental data, and it was determined that ...
