文章展示了一些使用铁磁流体的双流体流量控制的运动系统的例子。通过磁场控制磁流体在次级低粘性流体中的形状、位置和压力的变化,可以实现物体或磁流体本身的运动。在第一个例子中,物体的运动是由铁磁流体产生的次级流体流引起的,而在第二和第三种情况下,是由铁磁流体位置的直接改变引起的。
The article demonstrates some examples of locomotion systems with bifluidic flow control using ferrofluid. By controlling the change of shape, position, and pressure of the ferrofluid in a secondary low viscous fluid by magnetic fields locomotion of objects or the ferrofluid itself can be realized. The locomotion of an object is caused, in the first example, by a ferrofluid generated flow of the secondary fluid and in the second and third case by the direct alteration of the ferrofluid position.
