Water-based Fe2 O3 Ferrofluid Flow over a Rotatable Plate
Authors: ,
Abstract: In the current work, the influence of rotational viscosity as a result of an external magnetic field on water-based $$Fe_{2} O_{3}$$ ferrofluid flow over a rotating plate is investigated. The governing equations of the physical model are transformed into a set of ordinary differential equations. The numerical solution of the differential equations is obtained by using the finite element method. The findings of the radial, tangential, and axial velocity distributions are descriptively presented for the different range of rotational viscosity The outcomes of this research demonstrate that the magnetic field has an important role in controlling the velocity profiles in the flow. A comparative study of velocity distributions is presented for $$COFe_{2} O_{4}$$, $$Fe_{2} O_{3}$$, NiO, and CO nanoparticles.
