Study of magnetoviscous effects on ferrofluid flow

Abstract

Present results show the effect of magnetic field-dependent viscosity on the flow of magnetic fluid due to a non-conducting rotating disk. Shliomis model has been used in the problem formulation. A similarity transformation has been used to reduce a set of partial differential equations into nonlinear coupled differential equations. The nonlinear coupled differential equations involved in the problem are solved numerically through mathematical modeling in COMSOL Multiphysics. The radial, tangential, and axial velocity distribution is presented for different values of the magnetic field-dependent viscosity parameter. Some theoretical results used in the model have verified mathematically. These theoretical results are useful to validate the Shliomis model for rotational motion. The results indicate that the Shiliomis model is more appropriate to study the ferrofluid flow due to an infinite rotating disk in comparison to the Rosensweig model.
