An investigation on the enhancement of the thermal conductivity of water with the addition of multiwalled carbon nanotubes, (C-MWNT). C-MWNT occupied 0.6% of the volume in the test sample for every test repetition. Sodium dodecyl sulfate (SDS) was used as a dispersant. The measurement device was a transient hot wire, which was constructed for this purpose. The highest these procedures could raise the ...
Using a bare and a coated hot-wire apparatus, new data has been collected to determine the thermal conductivity of liquid water along the saturation line. This reference material data was collected with extremely high accuracy so the correlation presented is within revised a previous correlation that is endorsed by IUPAC, making it standard reference data....
This article summarizes the history of the development and improvements to the transient hot-wire technique. Starting with the discussions on “gas conduction”, and concluding with some modern applications, it covers the interactions of each component of the apparatus, including the cells, bridges, software employed and the theory development. The authors concludes the paper by outlining some issues with the current techniques and describes their recommendations for future advancements....
A study of the potential use of renewable resources to produce polyols, which in turn are used to produce polyurethane. The thermal conductivity of a number of results was taken using the TLS-100 device. This device functions using the transient line source method. A future increase in the production of polyurethane through renewable resources is imperative to reduce the consumption of fossil ...
Energy efficiency in old building is very dependent upon how much heat is escaping through the walls. To determine this it is imperative to know the thermal conductivity of certain solid stone walls. This paper focuses on investigating the properties of some types of common stones used in traditional masonry of Scotland. The TLS-100 device is used to calculate the thermal conductivity ...
