The present model aims to investigate the unsteady flow of CoFe2O4 nanofluid over a rotating and moving disk under the influence of the magnetic field. The magnetic body force is directed normal to the disk. The similarity transformation is employed to transform the governing equations into a set of nonlinear coupled differential equations. In the absence of a magnetic field and vertical movement of the disk, the problem reduces into Von Karman swirling flow problem. The nonlinear coupled differential equations in the present model are solved by the finite element method using the element size as 0.0001. In this numerical simulation, results for radial, tangential and axial velocity distributions are obtained for different values of physical parameters used in the model. A comparative study of different types of nanofluid is presented in the study and compared with CoFe2O4 nanofluid.
