Controlling pair dynamics of rotating magnetic microparticles through radial and transverse interactions
Dongfang Fu, Leilei Wang, Kailai Wang +2
Rotating magnetic microparticles are building blocks for field-driven assembly and microrobotic control. As the elementary interaction rule for larger assemblies, pair motion in th…
Dynamics of a microroller under confinement
Han Gao, Nan Xie, Zaiyi Shen +3
Rotating particles can translate when placed near a surface, forming microrollers with a wide range of biomedical and microfluidic applications. In this work, we investigate the dy…
Collective Flows Drive Cavitation in Spinner Monolayers
Zaiyi Shen, Juho S. Lintuvuori
Hydrodynamic interactions can give rise to a collective motion of rotating particles. This, in turn, can lead to coherent fluid flows. Using large scale hydrodynamic simulations, w…
Unsteady drag force on an immersed sphere oscillating near a wall
Zaicheng Zhang, Vincent Bertin, Martin Essink +6
The unsteady hydrodynamic drag exerted on an oscillating sphere near a planar wall is addressed experimentally, theoretically, and numerically. The experiments are performed by usi…
Reorientation dynamics of microswimmers at fluid-fluid interfaces
Harinadha Gidituri, Zaiyi Shen, Alois Wurger +1
We study the orientational and translational dynamics of spherical microswimmers trapped at fluid interfaces, in terms of the force dipole and source dipole components of their flo…
Inertial clustering and emergent phase separation of spherical spinners
Zaiyi Shen, Juho S. Lintuvuori
We study the hydrodynamics of spherical spinners suspended in a Newtonian fluid at inertial regime. We observe a spontaneous condensation of the spinners into particle rich regions…
