Research on the Magnetic Fluid Traveling Wave Pump under the Magnetic Field

磁场作用下的磁性流体行波泵研究是行波泵设计的基础。通过分析了行波磁场作用下的磁性流体的运动方程,从而进一步推导了行波磁场作用下的磁性流体的速度方程、旋转速度方程和单位时间内的流量方程,并通过实验进行了验证。研究表明:行波磁场作用下的磁性流体会产生流动现象;行波磁场作用下的磁性流体流量与磁极旋转的角度有直接关系,磁极旋转的角度越大,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,磁场越强,其流量越大;行波磁场的频率只能影响磁性流体的流速,对流量不产生任何直接影响。

The research on the magnetic fluid traveling wave pump under the magnetic field is the basic foundation for the design of the traveling wave pump on the magnetic fluid. According to the analysis of dynamical equations under the traveling wave magnetic field, the velocity equation as well as the spin velocity equation and flux equation per unit time, are also analyzed. The results are validated by experiments. The magnetic fluid under the traveling wave magnetic field produces the phenomenon of flowing. The flux of the magnetic fluid under the traveling wave magnetic field has a direct relationship with the rotating angle of the magnetic pole. Thus, larger angle of the magnetic pole results in the more flux is increased. The power of the traveling wave magnetic field could also have some effects on the flux of the magnetic fluid, the stronger the magnetic field becomes, the larger the flux is. The frequency of the traveling wave magnetic field could only affect on the velocity of flow of the magnetic fluid, but has no direct influence on the flux.
