Synthesis and Characterization of Copper-Copper oxide nanofluids in the confinement regime

Babukutty B., Parakkal F., Bhalero G.M., Nair S.S., Central University of kerala, IN

Abstract: Copper oxide shelled copper nanofluids are synthesized with surfactant trioctylphosphine oxide (TOPO) using sulphates precursors. The fluids were structurally characterised by X-ray Diffraction (XRD). Surface and morphological characterization are carried out by Scanning Electron [...]

Theoretical modelling of nanofluids for heat transfer

Myers T.G., Centre de Recerca, ES

In this talk we will discuss two uses of nanofluids for heat transfer: for cooling purposes and for absorbing solar thermal energy. In the first case we show that a popular theoretical model, which has [...]

Percolation theory at work – boosting the heat transfer performance of graphitic nanofluids

Timofeeva E.V., Singh D., Yu W., France D., Argonne National Laboratory, US

A plethora of studies have reported high thermal conductivity of nanofluids with high aspect ratio carbon nanoparticles such as graphenes and carbon nanotubes. Although many repot thermal conductivity enhancements in carbonaceous nanofluids there is no [...]

Mathematical modelling of nanoscale phenomena

Myers T.G., Font F., MacDevette M., Centre de Recerca Matematica, ES

The talk deals with 3 problems currently under investigation with the reesearch group at the Centre de Recerca Matematica: 1. Enhanced flow in carbon nanotubes. 2. Rapid melting of nanoparticles. 3. Enhanced heat transfer with [...]

Engineered Nanofluids for Heat Transfer and Novel Applications

Timofeeva E.V., Singh D., Yu W., France D., Argonne National Laboratory, US

Nanofluids are the new expanding area in nanotechnology, with applications as wide as biomedical, lubrication, thermal management, energy generation, energy conversion, and energy storage. Variety and unique characteristics of nanomaterials allow for engineering the multifunctional [...]

Possible explanations of the deviations in the thermal conductivity measurements

Han K., Lee M., Koo J., Kedzierski M.A., Kyung Hee University, KR

Nanofluids were invented to enhance thermal conductivity of the working fluid near the wall region, where the conduction is the only mechanism to dissipate heat and it limits the heat transfer rate from a body [...]

Modeling Thermophoresis (Soret Effect) in Nanofluids

Eslamian M., Ziad Saghir M., Texas A&M Univeristy- Corpus Christi, US

Thermophoresis plays an important role in forced and natural convection in channels and enclosures when nanofluids are used instead of pure fluids. Therefore, in order to be able to estimate the extent and role of [...]
