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 ...

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 ...

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 mm
2/g, specific surface area (SSA) of ...

This article examined how a variety of mechanisms (layering, Brownian motion, clustering, ballistic phonon motion, thermal boundary resistance, and mass difference scattering) affect the thermal conductivity of alumina based nanofluid. The thermal conductivity values were found using the transient plane source (TPS) method. It was found that mass difference scattering provided the most effective mechanism for reducing the thermal conductivity of the alumina based nanofluid....

Nanofluids are used to improve the thermal conductivity of heat transfer fluids. This study examined the effects on thermal conductivity of zinc oxide (ZnO)/ethylene glycol + water nanofluids as increasing concentrations of ZnO nanopartilces were added to the solution. A Thermal Constants Analyzer (TPS) measured the thermal conductivity of the nanofluids using the Transient Plane Source (TPS) method. As expected, the thermal conductivities of the solutions increased with nanoparticle concentration, ...
