Enhanced thermal conductivity of ethylene glycol-based suspensions in the presence of silver nanoparticles of various sizes and shapes

Silver (Ag) has the highest thermal conductivity of all metals, making it an attractive nanoparticle for use in heat transfer systems. The shape of nanoparticles influences their thermal conductivity, so three varieties of Ag nanoparticles were tested in this study. The Thermal Constants Analyser measured the thermal conductivity of Ag nanospheres (NSs), nanowires (NWs), and nanoflakes (NFs) between 10-30 °C using the transient plane source (TPS) method. Results showed that ...

Effects of melting temperature and the presence of internal fins on the performance of a phase change material (PCM)-based heat sink

Two organic phase change materials (PCMs) were investigated to determine their effects on the thermal management capabilities of electronics. The thermo-physical properties of n-eicosane and 1-hexadecanol were determined experimentally, and the two PCMs were then added to unfinned, and finned heat sinks. It was determined that a PCM with a high melting point is able to increase the time of protection from overheating; however, it was also determined that if ...

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 ...

An experimental investigation of melting of nanoparticle-enhanced phase change materials (NePCMs) in a bottom-heated vertical cylindrical cavity

A nanoparticle-enhanced phase change material (NePCM) is prepared by the dispersal of carbon nanotubes in 1-dodecanol. The objective of this experiment was to determine if the addition of nanoparticles could increase the thermal conductivity of the base PCM while resulting in a NePCM that would still have the required properties of a functional PCM. It was found that the thermal conductivity was enhanced through the addition of the carbon nanotubes; ...

Experimental Measurements of Thermal Conductivity of Wood Species in China: Effects of Density, Temperature, and Moisture Content

The authors selected 5 types of softwood species and 5 types of hardwood species that are commonly grown and used for construction in China for thermal analysis. Not only was thermal conductivity measured, but its dependence on moisture content, density and temperature of the wood samples was also investigated. Thermal conductivity was found to increase with increasing density of the wood sample and increasing moisture content. Thermal conductivity was also found to ...
