Magnetohydrodynamic radiative nanofluid flow over a rotating surface with Soret effect

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.
