Meshless Method Employing Magnetic Moment Method and Particle Method for Magnetic Fluid Motion Analysis

Abstract

Magneto hydro dynamics (MHD) phenomena exhibit complex behavior. In this paper, a new meshless analysis method employing the magnetic moment method and the particle method is proposed. The particle method is an analysis technique that can be used to calculate fluid motion by the dividing fluid into small particles. The magnetic moment method is an analysis technique in which the magnetic field is calculated by dividing ferromagnetic materials into small elements. In this study, the fluid particles in the particle method are treated as ferromagnetic material elements in the magnetic moment method. Therefore, the proposed coupling method does not require calculation points in the air space, i.e. remeshing of the entire space. In this paper, the proposed method is applied to analyze the behavior of a magnetic fluid under a magnetic field.

On the accurate large-scale simulation of ferrofluids

“…However, the ever-changing mesh topology impedes an efficient simulation. Mitsufuji et al [2016] also achieved the formation of a single bulge rather than multiple spikes using a particle method for simulating the fluid's dynamics. They formulated the magnetization problem as a system of linear equations as done in our work presented in this contribution.…”
