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…
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…
Caustic formation in a non-Gaussian model for turbulent aerosols
J. Meibohm, L. Sundberg, B. Mehlig +1
Caustics in the dynamics of heavy particles in turbulence accelerate particle collisions. The rate at which these singularities form depends sensitively on the Stokes…
Statistical models for the dynamics of heavy particles in turbulence
J. Bec, K. Gustavsson, B. Mehlig
When very small particles are suspended in a fluid in motion, they tend to follow the flow. How such tracer particles are mixed, transported, and dispersed by turbulent flow has be…
