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 ...
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 ...
The article investigated the hybridization of multi wall carbon nanotubes (MWCNTs) with filler in polymer matrix composites (PMC) which is one of the techniques used to combine different properties of fillers to make more unique composites. The properties of two different hybrid filler composites (Chemical Vapour Deposition (CVD) hybrid filler and physically hybrid filler) were then studied. The thermal conductivity was measured through the use of a Thermal Constant Analyzer ...
Many conventional fluids have low thermal conductivities. Adding thermally conductive nanometer-sized particles to these fluids transforms them into thermally conductive nanofluids. In this study, the thermal conductivity of aqueous alumina and multi-walled carbon nanotube (MWCNT) nanofluids was measured using the transient plane source (TPS) method with a thermal constants analyzer TPS. During each trial, 0.015 W of power were administered to each sample for two seconds. Results of the experiment showed ...
Many conventional fluids have low thermal conductivities. Adding thermally conductive nanometer-sized particles to these fluids transforms them into thermally conductive nanofluids that can be used for refrigeration and air conditioning systems. In this paper, the transient plane source (TPS) method is used to explore the thermal conductivity of multi-walled carbon nanotube (MWCNT) nanofluids in a helically coiled, double-pipe heat exchanger. The thermal conductivities of the MWCNT nanofluids were measured using ...
