Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
In the past twenty years, the behavior of the apparent thermal conductance of two or three phase systems comprised of solid particles with nanometer dimensions suspended in fluids, dubbed nanofluids, has been greatly contested in literature. After the study of the seven simplest nanofluids, Cu, CuO, Al2O3, and TiO2 suspended in water and ethylene glycol, ...
All reliable experimental data available relating to the viscosity and thermal conductance of water has been collected and turned into the current temperature scale and a set of units. There are four groups of data collected; liquid at ambient pressure, the rest of the liquid phase, the vapor phase, and the super-critical region. For each data point collected, a density was calculated theoretically. Viscosity was measured in the range of ...
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....
A detailed development of a local heat transfer probe specifically designed for analyzing nanofluids. In this paper iron oxide is used as a test subject to determine the accuracy of the probe. Different concentrations were measured ranging between 0 and 0.09% by volume. Thermal conductivity is also measured by a TLS-100 instrument, based on the transient line source. It is shown that the heat ...
