Buongiorno model for MHD nanofluid flow between rotating parallel plates in the presence of variable liquid properties

In this article, the effects of Brownian motion and thermophoresis on the flow, heat, and mass transfer from a rotating parallel plate is investigated. The Buongiorno mathematical model is considered and variable liquid properties are taken into account. MHD nanofluid terms are fused in the governing equations. Keller Box method is employed to solve the set of ordinary differential equations which are treated by suitable similarity transformations. A uniform step size of ∆ε = 0.01 is observed to be satisfactory with an error tolerance of 10⁻⁶. The graphical analysis of velocity, temperature, and concentration is presented. It is recorded that; upsurge in variable viscosity parameter diminishes the axial velocity however it has a twofold effect on transverse velocity. Furthermore, nanoparticle concentration and temperature are inversely related with reference to thermophoresis and Brownian motion parameters.
