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....
This article studied the thermal conductivity values and measurements for the following two systems using the transient hot wire (THW) and transient plane source (TPS) techniques: ethylene glycol with added CuO, TiO2, or Al2O3 nanoparticles and water with added TiO2 or Al2O3 nanoparticles or multiwall carbon nanotubes (MWCNTs). A TPS technique using a thermal conductivity analyzer ...
