| Abstract: | quations to calculate the distribution of magnetic field intensity in a cone space and the steady interface of the ferrofluid at rotating state were given with magnetic circuit method and simplified Navier-Stokes equation. Meanwhile the effects of sealing clearance, sealing angle and rotating speed on the sealing were also analysted. |
