Effect of Nonlinear Radiation on MHD Nanofluid Flow and Heat Transfer Due To Rotating Disk

A numerical study is developed to analyze the flow and heat transfer of rotating nanofluid with the inclusion of thermal radiation and magnetic field effects. Buongiorno model has been applied to incorporate Brownian motion and thermophoresis of the nanofluid. More realistic wall condition is applied which requires passive control of nanoparticle concentration at the disk. A set of non-linear ordinary differential equations are obtained from the governing partial differential equation with the aid of suitable similarity transformations. The resultant equations are then solved by Runge-Kutta-Felberg fourth and fifth order method along with shooting technique. The impact of several exciting physical parameters on the flow and heat transfer characteristics is analyzed through graphs and tables.
