Nanofluid

TL;DR: In this article, the effect of CuO-water nanofluid, as the working fluid, on the performance and the efficiency of a flat-plate solar collector is investigated experimentally.

TL;DR: In this paper, the effect of low nanoparticle volume fraction, ranging from 0.0055% to 0.278%, on density, thermal conductivity and viscosity of nanofluids is investigated for temperature range of 20 −40°C.

TL;DR: In this paper, an experimental study was performed to understand the nucleate boiling heat transfer of water-CuO nanoparticles suspension (nanofluids) at different operating pressures and different nanoparticle mass concentrations.

TL;DR: Heat transfer and flow analysis for a non-Newtonian third grade nanofluid flow in porous medium of a hollow vessel in presence of magnetic field are simulated analytically and numerically and show that increasing the thermophoresis parameter caused an increase in temperature values in whole domain and a increase in nanoparticles concentration just near the inner wall of vessel.

TL;DR: In this paper, the optical characterization of a new fluid consisting of single-wall carbon nanohorns and ethylene glycol for solar energy applications was reported, which showed that nanohorn spectral features are far more favorable than those of amorphous carbon for the specific application.
