Modeling bacterial flow field with regularized singularities
Yaochen Yang, Daiki Matsunaga, Da Wei +1
The flow field generated by a swimming bacterium serves as a fundamental building block for understanding hydrodynamic interactions between bacteria. Although the flow field genera…
Cell-induced wrinkling patterns on soft substrates
Aleksandra Ardaševa, Varun Venkatesh, Daiki Matsunaga +2
Cells exert traction forces on compliant substrates and can induce surface instabilities that appear as characteristic wrinkling patterns. Here, we develop a mechanical description…
Asymmetric bistability of chiral particle orientation in viscous shear flows
Andreas Zöttl, Francesca Tesser, Daiki Matsunaga +3
The migration of helical particles in viscous shear flows plays a crucial role in chiral particle sorting. Attaching a non-chiral head to a helical particle leads to a rheotactic t…
Field-controlling patterns of sheared ferrofluid droplets
Shunichi Ishida, Yaochen Yang, Fanlong Meng +1
We investigate how ferrofluid droplets suspended in a wall-bounded shear flow can organise when subjected to an external magnetic field. By tuning the magnitude of the external mag…
Degenerate states, emergent dynamics and fluid mixing by magnetic rotors
Takuma Kawai, Daiki Matsunaga, Fanlong Meng +2
We investigate the collective motion of magnetic rotors suspended in a viscous fluid under an uniform rotating magnetic field. The rotors are positioned on a square lattice, and lo…
Far-field theory for trajectories of magnetic ellipsoids in rectangular and circular channels
Daiki Matsunaga, Andreas Zöttl, Fanlong Meng +2
We report a method to control the positions of ellipsoidal magnets in flowing channels of rectangular or circular cross section at low Reynolds number.A static uniform magnetic fie…
Clustering of Magnetic Swimmers in a Poiseuille Flow
Fanlong Meng, Daiki Matsunaga, Ramin Golestanian
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 B…
Focusing and sorting of ellipsoidal magnetic particles in microchannels
Daiki Matsunaga, Fanlong Meng, Andreas Zoettl +2
We present a simple method to control the position of ellipsoidal magnetic particles in microchannel Poiseuille flow using a static uniform magnetic field. The magnetic field is ut…
