Measurements of thermal conductivity of solid eicosane-based NePCM

This paper aimed to measure the thermal conductivity of pure eicosane, eicosane-CuO and eicosane-MWCNTs solid composites. A Thermal Constants Analyzer measured the thermal conductivity of the nanostructure-enhanced PCMs using the transient plane source (TPS) method. Results showed that the thermal conductivity increased rapidly as the temperature of the solid composites approached the melting point. Additionally, the samples that were solidified in an oven, and the eicosane-MWCNT samples experienced the largest ...


Effect of radiative heat transfer on determining thermal conductivity of semi-transparent materials using transient plane source method

This study aimed to determine how reliable the Transient Plane Source (TPS) method is when testing semi-transparent materials that have varying extinction coefficients at different temperatures. A numerical experiment has been designed that copies the experimental process and tests the accuracy of the thermal conductivity values that the TPS method generates for semi-transparent materials. After using the TPS Method and comparing the results with the numerical experiment, the study concluded ...

Experimental Measurements of Thermophysical Properties of Al2O3– and TiO2–Ethylene Glycol Nanofluids

The thermal conductivity and dynamic viscosity of Al2O3-ethylene glycol and TiO2-ethylene glycol nanofluids have been determined as a function of the nanoparticle volume fraction (from 1 to 3 %) and temperature. It was determined that the thermal conductivity increased with increasing temperature as well as with increasing particle volume fraction for both types of nanofluids, but increasing the particle volume fraction caused a more significant increase than increasing the temperature. ...

Thermophysical Properties of Reconsolidating Crushed Salt 

The thermophysical properties of crushed salt were measured as it reconsolidated. The main focus of the work was to determine the thermal conductivity of the salt at temperatures ranging from -75 to 300ºC. It was determined that the thermal conductivity of reconsolidated crushed salt decreased with increasing porosity, but increased as the salt consolidated. At each porosity that was measured, the thermal conductivity was found to decrease with increasing temperature. ...

Chemical modification of tannin/furanic rigid foams by isocyanates and polyurethanes

Polymeric tannin/furanic foams fortified with polyurethane (PUR) and 4,4’ diphenylmethane diisocyanate (pMDI) were prepared. The thermo-physical and mechanical properties of the produced foams were investigated experimentally.  It was found that since there were a number of active isocyanate groups on the PUR that was used, there was no difference in adding PUR or pMDI to the foams, and so only the results for pMDI were presented. It was found that ...
