Three dimensional heat and mass transfer in a rotating system using nanofluid

In this study, three dimensional nanofluid flow and heat transfer in a rotating system in the presence of magnetic field is investigated. The important effects of Brownian motion and thermophoresis have been included in the model of nanofluid. The basic partial differential equations are reduced to ordinary differential equations which are solved numerically using the fourth-order Runge-Kutta method. The numerical investigation is carried out for different governing parameters namely: Reynolds number, Rotation parameter, Magnetic parameter, Schmidt number, Thermophoretic parameter and Brownian parameter. Results indicate that skin friction parameter increases with augment of Reynolds number, Rotation parameter and Magnetic parameter. Also it can be found that Nusselt number has a direct relationship with Reynolds number while it has a reverse relationship with Rotation parameter, Magnetic parameter, Schmidt number, Thermophoretic parameter and Brownian parameter.
