Resistance tensors for aggregate particles with Stokesian dynamics
J. Gissinger, G. Voth, B. Mehlig +1
The response of particles to low-Reynolds flow can be compactly predicted with resistance or mobility tensors. However, the difficulty of obtaining accurate values for the elements…
Bifurcations in Stokes Flow Sedimentation
Elias Huseby, Pierre Mathier, Meera Das +5
Particles whose shapes couple translation to rotation display a rich array of behaviors as they sediment at low Reynolds number. We introduce a unifying perspective in which the po…
Inertial rotation of a small oblate spheroid in a simple shear flow
Ziqi Wang, Xander M. de Wit, Davide Di Giusto +5
We compare experiments and fully-resolved particle simulations designed to match the experimental conditions of a weakly inertial, neutrally buoyant, moderately oblate spheroid in…
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…
