摘　　要：理论分析了磁性流体力学方程,为磁性流体解耦计算和应用奠定了理论基础.采用边界逐步逼近迭代法对磁场与力场问题进行解耦计算.行波磁场作用下的磁性流体流量与产生行波磁场的永磁转子的磁极旋转的角度有直接关系,永磁转子磁极旋转过的角度越大,其流量也越多;行波磁场的强弱对磁性流体流量也会产生影响,当永磁转子磁极旋转相同角度时,磁场越强,其流量越大;在永磁转子旋转相同角度时,行波磁场的频率只能影响磁性流体的流速,对流量不直接产生影响.The magnetic hydrostatic equation and the magnetic hydrodynamics equation are investigated as a basic theory which lays the cornerstone for decoupled computation and application. The method used for decoupled computation is the Boundary-Step by step-Hand and hand Iterative Method. Under the effect of traveling wave magnetic field, the flux of magnetic fluid has a direct relationship with the rotating angle of magnetic pole of the permanent magnetic rotor which is used to produce traveling wave magnetic field. The flux increases with the enlarged rotating angle of the permanent magnetic rotor. The intensity of traveling wave magnetic field also influences the magnetic fluid flux. At the same rotating angle of the magnetic pole of permanent magnetic rotor, the flux increases with the strengthened magnetic field; the frequency of traveling magnetic field only affects： the flow velocity of magnetic fluid, and it has no direct influence on the flux.
