Numerical analysis of the behavior of magnetic fluid in traveling magnetic field using the ALE GSMAC FEM

摘要

Abstract. Flow field in a thin layer of magnetic fluid under traveling magnetic field is investigated using the ALE type ofnGSMAC finite element method. Numerical results are qualitatively agree well with the experimental results reported by H.nKikura [1]. Relation between flow field and volume transportation of fluid is reported. It is shown that the surface velocity isnmaximized at the certain depth of magnetic fluid layer in case of low frequency of traveling magnetic field.
