Abstract
In the present case, we have studied the effect of magnetic field-dependent viscosity (MFD) along with porosity on the revolving Axi-symmetric steady ferrofluid flow with rotating disk by solving the boundary layer equations using Neuringer-Rosensweig (NR) model. Here, we have calculated the velocity components and pressure for different values of MFD viscosity (k) and porosity (ε) with the variation of Karman’s dimensionless parameter α. Also, we have calculated the displacement thickness of the boundary layer and total volume flowing outward the z-axis. The numerical results which are obtained for various flow characteristics are shown graphically.
