Measurement on thermal conductivity of compacted GMZ001 bentonite

This article looks at GMZ deposits as a candidate for buffer material of high-level radioactive wastes (HLW) in china. A thermal analyzer was used to measure thermal conductivity of compacted GMZ001 bentonite using the transient plane source technique. Results found that for samples having the same weight percentage of dry and wet density, thermal conductivity increased as the water content increased....

Preparation and thermal properties of polyethylene glycol/expanded graphite blends for energy storage

Through the addition of expanded graphite (EG) to polyethylene glycol, the authors were able to enhance the thermal conductivity of the phase change material (PCM). The transient plane source (TPS) technique was used to measure the thermal conductivity of the PCM. The amount of EG affected thermal conductivity, while amount of polyethylene glycol affected latent heat. Through the use of EG, the thermal conductivity was raised fourfold.....

Thermal properties of pineapple leaf fiber reinforced composites

Varying weight percentages of pineapple leaf fiber were added to phenolformaldehyde (PF) in order to generate a composite material. Using the transient plane source (TPS) technique, the thermal conductivities of the varying weight percentage composites were studied. It was found that increasing weight % pineapple leaf fiber resulted in decreasing thermal conductivity and diffusivity of the composites. The experimental results are compared to results produced by two models (the Rayleigh-Maxwell and ...

Simultaneous determination of thermal conductivity and thermal diffusivity of food and agricultural materials using a transient plane-source method

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....

Influence of pH on Nanofluids- Viscosity and Thermal Conductivity

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. ...
