Influence of Field Frequency to Rotating Ferrofluid Drops and Oscillating Micro–bead chains

碩士 === 國立交通大學 === 機械工程系所 === 104 === We experimentally investigate the motion of a ferrofluid drop in a rotating magnetic field. Magnetized and driven by the external field, the drop would be stretched to the shape of ellipsoid along the orientation of the field. It is observed that the stretched le...

Magnetized and driven by the external field, the drop would be stretched to the shape of ellipsoid along the orientation of the field. It is observed that the stretched length of drop decreased when we increase the frequency of the external field. And we use two dimensionless parameters to know the influence of field frequency clearly. Besides, compare these results to the micro-bead chain which subjected to an oscillating field. The amplitude of the chains decreased when we increase the frequency of the oscillating field. Chen, Ching-Yao 陳慶耀 2016 學位論文 ; thesis 67 zh-TW
