Experimental study on thermo physical properties of capillary wicks for loop heat pipe 

In this study, loop heat pipe capillary wicks were prepared and the transient plane source (TPS) method measured the thermal conductivity, thermal diffusivity, and specific heat of the samples. The results showed that thermal conductivity increased with porosity, but porosity seemingly had no effect on diffusivity and specific heat....

A comprehensive characterization on the structural and thermophysical properties of sintered ore particles toward waste heat recovery applications

Thermophysical and structural properties of sintered ore particles (SOPs) were determined to expand upon the little documented information there is regarding the properties of these materials. In addition to this, a fractal model was also developed for the prediction of thermal conductivity in SOPs as a function of porosity. The experimental results revealed that the specific heat capacity increased with increasing temperature and that the thermal conductivity decreased with increasing ...

Preparation of silica aerogel/polyurethane composites for the application of thermal insulation

The authors prepared silica aerogel/polyurethane composites by two different methods for the comparison of the two methods. The objective was to study the thermal insulation and hydrophobic properties of the composites to evaluate their potential for use as fabric membranes. It was found that the composites are better thermal insulators than polyurethane alone, and that they also have improved hydrophobic properties. It was also determined that the thermal conductivities ...

Closed-cell carbon foams from diphenolic acid-based polybenzoxazine

Carbon foams were prepared from diphenolic acid-based benzoxazine foams by pyrolysis under nitrogen atmosphere. The method used in this article produced foams containing a large fraction of closed cells which is uncommon for carbon foams. The foams studied were found to possess similar mechanical properties common to other carbon foams; however, the presence of the high fraction of closed cells led to the lowest observed thermal conductivity ever reported for ...

Properties of Nanocrystals-formulated Aluminosilicate Bricks

Seven different types of nanocrystals were used as additives in aluminosilicate bricks to determine if this is a valid method of decreasing the thermal diffusivity of the bricks for use as plant coating in the iron and steel industries. Each type of nanocrystal was added in  concentration percentages of 0.5, 1, and 2 wt. % to determine the effect of concentration on thermal transport and physical properties. It was found that all of the ...
