Two-way coupling in active suspensions suppresses particle accumulation and induces non-monotonic flow stabilization
Miyi Wu, Ziyue Yu, Lei Fang
We experimentally study the two-way coupling between a swarm of centimetre-scale active swimmers (Artemia salina) and an electromagnetically driven quasi-two-dimensional cellular f…

Turbulence at Low Reynolds Numbers
Ziyue Yu, Xinyu Si, Lei Fang
Turbulence -- ubiquitous in nature and engineering alike [1-5] -- is traditionally viewed as an intrinsically inertial phenomenon, emerging only when the Reynolds number (Re), whic…
