Numerical simulation of laminar to turbulent nanofluid flow and heat transfer over a backward-facing step

作者：

Highlights：

• Finite volume method based on shear stress transport (SST) K–ω Model employed in this paper.

• Enhancement of heat transfer with the increase of nanoparticle concentration and Reynolds number observed.

• The effect of expansion ratio was clearly observed at the downstream inlet region.
