旋转型磁性流体行波泵仿真研究

Simulation Research of Spin Traveling Wave Pump on Magnetic Fluid

以旋转型磁性流体行波泵为研究对象,理论分析了旋转磁场作用下磁性流体特性和压强的关系。通过磁场和力场解耦计算分析旋转磁场作用下磁性流体的运动特性、磁场特性以及与压强的关系。用实验验证分析计算的科学性和合理性。在旋转磁场的作用下,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;磁性流体在泵腔内会产生流动的现象;随着磁场的不断增强,磁性流体的流量也不断增加。

According to researching the spin traveling wave pump,the relationship of the characteristics of magnetic fluid and the press is investigated under the spin magnetic field by the theory method.The relationship of moving,magnetic field and press is investigated by the decoupled computation between the magnetic field and force.The method is scientificity and rationality by the testing.The distributing shape of magnetic fluid in the pump is affected by the adding magnetic field under the spin magnetic field when the magnetic fluid is filled in the pump.At the same time,the adding magnetic field is affected by magnetic particles of magnetic fluid.The magnetic fluid can be moved by the effect of the adding magnetic field in the pump.The flux of magnetic fluid increases with the magnetic field.
