Heat and Mass Transfer in 3D Non-Newtonian Nano and Ferro Fluids over a Bidirectional Stretching Surface

Abstract

An analysis has been carried out for three-dimensional flow of magneto hydrodynamic Sisko ferro and nanofluids over a bidirectional stretching surface in porous medium with non-uniform heat source/sink. The set of nonlinear governing partial differential equations are transformed in to ordinary differential equations by using self-suitable transformations, and solved numerically using Runge-Kutta and Newton’s methods. The acquired results presents the effects of various non-dimensional governing parameters on velocity and temperature profiles. Also, determined and analyzed the friction factor coefficients and local Nusselt number. We have presented dual solutions for Sisko ferro and nanofluid cases. An excellent agreement of the present results has been found with existed literature under some special limited cases. Results depict that the material parameter have tendency to boost the friction factor coefficients along with the heat transfer rate. It is also observed that the heat transfer performance of Sisko nanofluid is high while compared with the heat transfer performance of the Sisko ferro fluid.
