Magnetohydrodynamic radiative nanofluid flow over a rotating surface with Soret effect

Abstract

Purpose – The purpose of this paper is to theoretically investigate the boundary layer nature of magnetohydrodynamic nanofluid flow past a vertical expanding surface in a rotating geometry with viscous dissipation, thermal radiation, Soret effect and chemical reaction. Design/methodology/approach – The self-similarity variables are deliberated to transmute the elementary governing equations. The analytical perturbation technique is used to elaborate the united nonlinear ODEs. Findings – To check the disparity on the boundary layer nature, the authors measured two nanofluids, namely, Cu-water and Cu-Kerosene based nanofluids. It is found that the Cu-water is effectively enhancing the thermal conductivity of the flow when compared with the Cu-kerosene. Originality/value – Till now no analytical studies are reported on heat transfer enhancement of the rotating nanofluid flow by considering two different base fluids. © Emerald Publishing Limited.
