Guided navigation in turbulence
Jingran Qiu, Kristian Gustavsson
Navigation in turbulence is challenging because local flow measurements provide limited information about favorable paths beyond the flow correlation scales. We investigate vertica…
Multi-agent rendezvous in fluid flows via reinforcement learning
Bocheng Li, Jingran Qiu, Lihao Zhao
Rendezvous is a critical task for multi-agent systems, requiring agents to coordinate to meet at an unspecified location. However, achieving this in fluid environments presents a c…
Adaptive shape control for microswimmer navigation in turbulence
Jingran Qiu, Lorenzo Piro, Luca Biferale +3
Navigation in turbulent environments is a fundamental challenge for biological and artificial microswimmers. While most existing studies focus on adapting motility or steering, the…
Short term vs. long term: optimization of microswimmer navigation on different time horizons
Navid Mousavi, Jingran Qiu, Lihao Zhao +2
We use reinforcement learning to find strategies that allow microswimmers in turbulence to avoid regions of large strain. This question is motivated by the hypothesis that swimming…
Efficient survival strategy for zooplankton in turbulence
Navid Mousavi, Jingran Qiu, Bernhard Mehlig +2
Zooplankton in a quiescent environment can detect predators by hydrodynamic sensing, triggering powerful escape responses. Since turbulent strain tends to mask the hydrodynamic sig…
Active gyrotactic stability of microswimmers using hydromechanical signals
Jingran Qiu, Navid Mousavi, Lihao Zhao +1
Many plankton species undergo daily vertical migration to large depths in the turbulent ocean. To do this efficiently, the plankton can use a gyrotactic mechanism, aligning them wi…
Navigation of micro-swimmers in steady flow: the importance of symmetries
J. Qiu, N. Mousavi, K. Gustavsson +3
Marine microorganisms must cope with complex flow patterns and even turbulence as they navigate the ocean. To survive they must avoid predation and find efficient energy sources. A…
Fluid inertial torque is an effective gyrotactic mechanism for settling elongated micro-swimmers
Jingran Qiu, Zhiwen Cui, Eric Climent +1
Marine plankton are usually modeled as settling elongated micro-swimmers. For the first time, we consider the torque induced by fluid inertia on such swimmers, and we discover that…
Swimming strategy of settling elongated microswimmers by reinforcement learning
Jingran Qiu, Weixi Huang, Chunxiao Xu +1
Particular types of plankton in aquatic ecosystems can coordinate their motion depending on the local flow environment to reach regions conducive to their growth or reproduction. I…
