Nanofluid convection taking into account the Soret effect and its impact on heat transfer and fluid flow

The present study is a numerical simulation of natural convection in nanofluids, within in a square cavity differentially heated, to identify the fluid flow and heat transfer by considering the Soret effect during which a temperature gradient in a binary mixture gives rise to a concentration gradien...
