Abstract

In this paper, we study a new analysis method to calculate the shape of ferrofluid spikes. The shape of a ferrofluid is influenced by the magnetic force, surface force, and gravity. Therefore, the electromagnetic field equation is coupled with Navier-Stokes equation employing the moving particle semi-implicit (MPS) and the finite-element method (FEM). This paper describes the analysis algorithm of coupled method, and the comparison of calculated and measured results.
