This paper explains an addition to a larger NPL project with the purpose to validate the use of the transient contact-probes for measurement of the thermal conductivity of soft solids such as foods, powders, and biological materials. Transient line source methods are used in this paper to accurately measure the thermal conductivities of a large variety of materials. More attention is paid ...
In an attempt to understand the numerous physical aspects of mines, a numerical modeling simulation on the development and dewatering of mines has been presented. The transient line source was used to complete this task. The log approximation was used to find the change in flow rate per unit length of the tunnel....
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 GNP. ...
