Clustering of magnetic swimmers in a Poiseuille flow

Physical Review Letters American Physical Society 120:18 (2018) 188101

Authors:

Fanlong Meng, Daiki Matsunaga, Ramin Golestanian

Abstract:

We investigate the collective behavior of magnetic swimmers, which are suspended in a Poiseuille flow and placed under an external magnetic field, using analytical techniques and Brownian dynamics simulations. We find that the interplay between intrinsic activity, external alignment, and magnetic dipole-dipole interactions leads to longitudinal structure formation. Our work sheds light on a recent experimental observation of a clustering instability in this system.
