Analysis of driving capacity on traveling wave pump of magnetic fluid

The decoupled question of magnetic fluid and magnetic field is investigated by the Boundary-Step by Step Hand Method. The magnetic field intensity and the saturation magnetization of magnetic fluid affect driving capacity of magnetic fluid traveling wave pump directly. The driving capacity increases increasing of the magnetic field intensity and the saturation magnetization of magnetic fluid. The viscosity of the magnetic fluid affects the driving capacity too. The viscosity of magnetic fluid can change when the magnetic field changes. The viscosity increases when magnetic field increases. When magnetization of magnetic fluid reaches saturation, the viscosity changes tardily. The driving capacity reduces with the increasing of the viscosity. The shape of the magnetic pole affects the driving capacity. The magnetic induction in the pump can be changed with the changing on the shape of magnetic pole. The driving capacity is max when the pole angle is 450.
