摘要
磁性流体行波泵内填充磁性流体后,外加磁场对磁性流体在泵腔内的分布产生影响,同时由于磁性流体内磁性颗粒的存在对外加磁场也会产生影响,采用迭代解耦计算法分析直线型磁性流体行波泵中磁场和力场的耦合问题。在行波磁场的作用下,磁性流体会产生流动的现象,随着磁性流体饱和磁化强度的不断提高,磁性流体的流速也不断提高;随着磁场强度的增强,磁性流体的流量增大。泵腔中心线处的压强差最大,两侧处的压强差最小;泵腔中心线处的速度变化率最大,两侧处的速度变化率最小;相同的时间间隔内,泵腔中心线处的速度最快,向两侧处的速度逐渐降低,两侧处的速度最低。
The applied magnetic field affects the distributing shape of magnetic fluid.According to the magnetic particles of the magnetic fluid,the adding magnetic fluid is affected.The decoupled question between the magnetic field and force is solved by the boundary-step by step-hand and hand iterative method.The stream of magnetic fluid is produced by the traveling wave magnetic field.The velocity of the magnetic fluid can increased with the increasing saturation magnetization and magnetic field.The difference press is maximum in the center line of pump,and the difference is minimum in the edge of pump.The acceleration is maximum in the center line of pump,and the acceleration is minimum in the edge of pump.The velocity of center line is maximum,and the edge is minimum with the same time interval.The velocity of magnetic fluid reduces from the center line to edge.
