摘要
利用磁路方法和简化的Ｎａｖｉｅｒ－Ｓｔｏｋｅｓ方程，导出了锥形空间内磁场强度分布和旋转时铁磁流体稳定界面的计算方程。分析了密封间隙、密封角和转速对密封能力的影响。
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.
