Abstract

Abstract Theoretically, the velocity distributions of the sealed liquid and magnetic fluid are studied. The velocity of the sealed liquid and magnetic fluid decreases nonlinearly with the increase of the radius. The instability of the interface between magnetic fluid and the sealed liquid is studied. Experimentally, when the rotating speed of the shaft increases, magnetic fluid and the sealed liquid are mixed with each other, and the stability of the interface between magnetic fluid and the sealed liquid is destroyed. The higher the rotational speed of the shaft is, the shorter the time for the interface to remain stable is.
