Seven distinct samples of nanofluids consisting of different concentrations of spherical graphitized carbon black in an ethylene glycol solution were analyzed to determine their thermal and rheological behavior. The thermal conductivity measurements were made at 20°C and 30°C with a transient hot wire instrument made by Thermtest called THW-L2 and specifically designed to measure the thermal conductivity of liquids. This study was ...
This paper attempts to expand the data for the thermal properties of materials used in 3D printing, which was considered limited before. This new data set may be useful in accelerating new developments and designs of heat exchangers. The effect of layer height and width are accounted for in the presented measurements. It is shown from varying these dimensions that as the layer height and width increase the thermal conductivity ...
Safety tests were conducted on cesium-loaded spherical resorcinol formaldehyde (SRF), resulting in a possible reclassification of the fire safety for the Cesium Ion Exchange Process System (CXP) emergency elution vessels, equipment, and piping. One of these tests was to determine the thermal conductivity using the transient line source technique, as thermal conductivity is a very important quantity for the safe treatment of materials....
Kerosene graphene nanoplatelets (GNP) nanofluids have a potential use in regenerative cooling of semi-cryogenic rocket thrust chamber. Before they can be used, more must be known about this substance's physical qualities. This study focuses on finding the effective thermal conductivity of this type of nanofluid, specifically at .005, 0.05 and 0.2 weight percentage (wt%) and 300, 500 and 750 mm2/g, specific surface area (SSA) of ...
Insulating materials were made from recycled clay waste using technologies developed by the author were tested for their thermal conductivity using the transient line source technique over a temperature range of 0-60°C. The clay used was mainly composed of kaolinite. A weight reduction was obtained by using wood aggregates. Different weight percentages of wood aggregates (0, 25, 30, 40, 50%) and the thermal conductivity curves are ...
