Investigating ferro-liquid flow in a rotating and stretching deformed cone

The motion of a hydro-ferro-liquid in a rotating and stretching deformed cone is investigated in this study. We use the similarity variable for velocity and temperature distribution to simplify and dimensionalize the governing equations of ferrohydrodynamic flow. The finite element technique in COMSOL Multiphysics is employed to numerically work out the reduced similarity equations for velocity and temperature. Magnetic viscosity is generated in the flow as a result of the cone rotating under the influence of the magnetic field. We examine the velocity and temperature fields for various values of ferromagnetic interaction numbers, cone deformation rate, and Eckert number. Furthermore, we look at how these variables affect local heat transfer and stress on the cone's surface. The current findings may be applied realistically to enhance the spinning shaft's sealing. Controlling the heat in electronic devices can also benefit from the current behavior of ferrohydrodynamic flow.

Automated summary

This study investigates the motion of a hydro-ferro-liquid in a rotating and stretching deformed cone. The governing equations of ferrohydrodynamic flow are simplified and dimensionalized using similarity variables for velocity and temperature distribution. The numerical solution of the reduced similarity equations for velocity and temperature is obtained using the finite element technique in COMSOL Multiphysics. The results show that magnetic viscosity is generated in the flow due to the rotation of the cone under the influence of the magnetic field. The study examines the velocity and temperature fields for different parameters and analyzes their effects on local heat transfer and stress on the cone's surface.
