Heat transfer in magnetohydrodynamic nanofluid flow past a circular cylinder
K S Arjun,K Rakesh +1 more
TL;DR: In this article, the authors investigated the relationship between flow behaviors and force variations due to the influencing parameters and found that the control of flow over a circular cylinder for heat transfer enhancement using different parameters significantly changes vortical structures in the wake and reduces mean drag and lift fluctuations, destabilizes the shear layer and reattaches the flow on the surface before main separation.

Convective Transport in Nanofluids
TL;DR: In this article, the authors considered seven slip mechanisms that can produce a relative velocity between the nanoparticles and the base fluid and concluded that only Brownian diffusion and thermophoresis are important slip mechanisms in nanofluids.
