TLDR
In this article, an apparently paradoxical behaviour of heat transfer deterioration was observed in nano-fluid and its dependence on parameters such as particle concentration, material of the particles and geometry of the containing cavity have been investigated.Abstract:
Fluids with nano size solid particles suspended in them have been given the name nano-fluid which in recent studies have shown tremendous promise as heat transfer fluids. However, before suggesting such fluids for applications a thorough knowledge of physical mechanism of heat transfer in such fluids is wanted. The present study deals with one such aspect of natural convection of nano fluids inside horizontal cylinder heated from one end and cooled from the other. An apparently paradoxical behaviour of heat transfer deterioration was observed in the experimental study. Nature of this deterioration and its dependence on parameters such as particle concentration, material of the particles and geometry of the containing cavity have been investigated. The fluid shows characters distinct from that of common slurries.read more

Numerical Model for Heat Transfer Analysis of Heavy Earth Moving Machinery Nanofluids Coolant
TL;DR: In this article, a numerical model has been developed for evaluating thermal performance of nanofluid and a Rayleigh dimensionless approach has been used to develop this model, which has shown that Al2O3 nanoparticles showed better thermal behavior than compares with Fe2O 3 and CuO nanofluid at the same volume fraction.

Anomalously increased effective thermal conductivities of ethylene glycol-based nanofluids containing copper nanoparticles
TL;DR: In this paper, it was shown that a "nanofluid" consisting of copper nanometer-sized particles dispersed in ethylene glycol has a much higher effective thermal conductivity than either pure or pure glycol or even polyethylene glycol containing the same volume fraction of dispersed oxide nanoparticles.
