Numerical Solution of Rotating Flow of a Nanofluid Over a Stretching Surface in the Presence of Magnetic Field

In this article, the flow of a nanofluid with water as the base fluid and Cu and Ag as the nanoparticles has been considered between two rotating plates. The upper plate has been considered porous. In addition, the bottom surface is assumed to move with variable speed to cause the forced convection. Centripetal and Coriolis forces effects on the rotation of the fluid are also considered. The set of non-dimensional ordinary differential equations is obtained by applying some appropriate transformations on the governing partial differential equations. Numerical solution of the system of nonlinear ODEs is obtained through the shooting method. It is theoretically observed that the nanofluid has a higher heat transfer rate and less drag as compared with the base fluid. Impact of rotation makes the drag rise and diminishes the Nusselt number independent of the various essential parameters used. Streamlines have been displayed to show the effect of injection/suction.
