Experimental Study of CuO/Water Nanofluid Turbulent Convective Heat Transfer in Square Cross-section Duct
TL;DR: In this article, the convective heat transfer for a CuO/water nanofluid through a square cross-section duct in the turbulent flow regime has been investigated, and the results show considerable enhancement in the heat transfer coefficient and Nusselt number by increasing the nanoparticle concentrations as well as the Peclet number.

An experimental investigation, sensitivity analysis and RSM analysis of MWCNT(10)-ZnO(90)/10W40 nanofluid viscosity
TL;DR: In this article, the viscosity of MWCNT (%10)-ZnO (%90)/10W40 hybrid nanofluid is examined in different volume fractions (0.05% −1%), temperatures (5 −55°C), and shear rates (666.5 −11,997 −1).

Performance Augmentation and Optimization of Aluminum Oxide-Water Nanofluid Flow in a Two-Fluid Microchannel Heat Exchanger
TL;DR: In this paper, the authors investigated laminar forced convection and entropy generation in a counter flow microchannel heat exchanger (CFMCHE) with two different working fluids in hot and cold channels, i.e., pure water and Al2O3-water nanofluid, using a three-dimensional conjugate heat transfer model.
Journal ArticleDOI
Boiling local heat transfer enhancement in minichannels using nanofluids
TL;DR: The boiling local heat transfer enhancement by adding silver nanoparticles in base fluid is not uniform along the channel flow, and better performances and highest effect of nanoparticle concentration on the heat transfer are obtained at the minichannels entrance.

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.
