Nanofluid

TL;DR: In this article, the authors revisited their previous model and extended it to the case when the nanofluid particle fraction on the boundary is passively rather than actively controlled, which makes the model physically more realistic than their previous models.

TL;DR: In this article, the most recent advances of nanofluids in thermal energy storage systems, solar collectors, solar stills, and photovoltaic/thermal systems are presented.

TL;DR: In this article, the effects of the nanoparticle volumetric concentration and inlet fluid velocity on the efficiency and heat transfer enhancement of a water-cooled photovoltaic thermal collector were simulated.

TL;DR: In this paper, the effects of nanoparticle concentration, shear and buoyancy forces, and turbulence on flow and thermal behavior of nanofluid flow were studied, and the model predictions for very low solid volume fraction were found to be in good agreement with earlier numerical studies for a base fluid.

TL;DR: In this article, the authors made an attempt to cover the latest experimental studies performed on the viscosity of nanofluids and found that the real effects of volume fraction, temperature, particle size, and shape on the viscous properties of nanoparticles can be determined through experiments.
