Vortical regions in flows can trap microorganisms over time scales that may affect their mortality and growth by inhibiting foraging, exploration, and predator avoidance. In this work, we analyse the dynamics of a spherical microswimmer in a vortical flow, and show how the trapping region is affected by changes in swimming speed and turning speed. We identify a critical swimming speed above which the trapping region vanishes, and show that active turning can lower this critical speed. Using these results, we explain how the choice of swimming parameters affects the success rate of microswimmers trained to escape the trapping region through reinforcement learning.
I'm a fifth-year PhD student in the Statistical Physics group with Bernhard Mehlig as supervisor. My research focuses on dynamical systems theory, neural networks, and coherent structures in fluids.
