Potential applications of nanofluids for heat transfer

Multiple studies claiming the usefulness of nanofluids for the enhancement of heat transport have been proven ill-founded. Although they have significantly raised thermal conductivities, there is an inerrant increase in viscosity when adding nanoparticles to a liquid. This paper explores areas of research that analyze nanofluid properties that could potiential indicate future applications. A promising direction is using particles that can change ...

Reference Data for the Thermal Conductivity of Saturated Liquid Toluene Over a Wide Range of Temperatures

Liquid toluene is a material used in industrial processes, and generally the thermal conductivity needs to be determined for efficient use. However, the thermal conductivity varies depending on high temperatures and other physical variables. The transient hot wire method has previously been used to obtain measurements of the thermal conductivity of toluene under multiple conditions to create reference data. This paper displays ...

Thermal conductivity of nanofluids – Experimental and Theoretical

The use of the transient hot wire method has previously displayed that the thermal conductivity of fluids can be significantly increased by introducing nano-particles. The paper discusses the known methods for predicting the thermal conductivity and finding correlations amongst data. When preforming initial simulations employing the Finite Element Method (FEM), this paper shows that there is still substantial experimental progress to be ...

Thermal Conductivity of Suspensions of Carbon Nanotubes in Water

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 ...

Standard Reference Data for the Thermal Conductivity of Water

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....
