磁流体在轴向磁场中突出峰结构的实验研究

Experimental investigation of the prominent structure of ferromagnetic fluid in axial magnetic field

系统地研究了少量铁磁性流体在轴对称磁场中,液-气表面所形成的三维突出峰结构.通过实验的方法探究了外加磁场强度、流体体积、流体黏度等对流体突出峰结构特征的影响.在理论方面,从空间势场与流体表面相互耦合的角度,对流体表面产生三维突出峰结构的机理,进行了分析.

The structure of a three-dimensional peak of a small amount of ferromagnetic fluids in an axisymmetric magnetic field had been systematically investigated. The effects of external magnetic field strength, fluid volume and fluid viscosity on the peak structure were investigated by experimentally. The mechanism of the three-dimensional peak structure on the surface of fluid was analyzed theoretically in view of the coupling between the potential field and the fluid surface.
