Two different sets of phase change materials were made by adding either graphene or exfoliated graphite nanoplatelets (xGnP) to paraffin in hot toluene. The thermal and stability properties of these newly synthesized composites were then studied using the TPS method. The addition of xGnP led to a higher thermal conductivity while the addition of graphene led to a higher electrical conductivity. Graphene was found to be better at stabilizing the ...
Using the TPS method, the thermal conductivities of a variety of metallic hollow sphere structures (MHSS) were measured. The thermal conductivities were also calculated using Misnar's analytical model and compared to the experimental results, with good agreement between the two sets of data....
Since there was no literature on using the transient plane source method for the measurement of thermal conductivity and diffusivity of food products the authors did it themselves. They tested a variety of products including water, mineral oil, ethanol, beef, chicken and apples and determined that using the transient plane source method to simultaneously measure thermal conductivity and diffusivity was an accurate method....
This article outlines the effect of adding Al2O3 and Cu nanoparticles to water and measuring the thermal conductivities and viscosities of the mixtures. The effect of pH was taken into account and it was found that there are optimal pH values for each of the nanoparticle mixtures that give the highest thermal conductivities and lowest viscosities. Research shows that thermal conductivity and viscosity are closely related to each other. ...
Two different types of carbon (synthetic graphite particles and carbon fiber) were added to nylon 6,6 and then these composites were tested using the transient plane source method in order to determine the through-plane and in-plane thermal conductivities. The thermal conductivities were found to be proportional to the volume percent of carbon added. A simple empirical model was also developed in order to estimate in-plane thermal conductivities for a range of ...
