New Measurements of the Apparent Thermal Conductivity of Nanofluids and Investigation of Their Heat Transfer Capabilities

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 ...

Rheological and Thermal Transport Characteristics of a Transformer Oil Based Ferrofluid

This article studied the flow and thermal transport characteristics of a ferrofluid based on transformer oil (Mogul Trafo CZ-A) and iron oxide nanoparticles. The thermal conductivity, specific heat, and thermal diffusivity were calculated using the transient plane source (TPS) method and a thermal constants analyzer was used for performing the measurements. It was found that the presence of the magnetic nanoparticles in the transformer oil (3%) increased its thermal conductivity by ...

Nitrogen doped hybrid carbon based composite dispersed nanofluids as working fluid for low-temperature direct absorption solar collectors

This article studied the thermal conductivity of deionized (DI) water and ethylene glycol (EG) based nanofluids with varying temperatures for different volume fractions of N-(rGO-MWNTs) (nitrogen doped hybrid structure of reduced graphene oxide (rGO) and multiwalled carbon nanotubes (MWNTs)). The thermal conductivity was found by using the transient plane source (TPS) method by using a Thermal Analyser. From the experimental results, it was noted that the thermal conductivity of ...

Enhancement of heat transport in oscillating heat pipe with ternary fluid

An oscillating heat pipe (OHP) is a pipe that transports heat from the evaporator to the condenser via a complex pulsating action. Nanofluids and self-wetting fluids can be used to improve the heat transport capabilities of the OHPs. This study looks at heat transport performances of OHP with different binary fluids. Thermal conductivity was measured using a thermal analyzer, with transient plane source method. Nanofluids were found to have a ...

The characteristics of convective heat transfer in microchannel heat sinks using Al2O3 and TiO2 nanofluids

Nanofluids are heat transfer fluids with enhanced thermal conductivity properties due to the addition of metallic-based nanoparticles. In this study, the thermal properties of Al¬2O3 and TiO2 nanofluids were examined to evaluate their usefulness in microchannel heat sink applications. A thermal constants analyzer measured the thermal conductivity of the nanofluids using the transient plane source (TPS) method. Results showed that thermal conductivity increased with volume fraction of nanofluids, and ...
