Rheotaxis of spheroidal squirmers in microchannel flow: Interplay of shape, hydrodynamics, active stress, and thermal fluctuations
Kai Qi, Hemalatha Annepu, Gerhard Gompper, Roland G. Winkler
Abstract
The authors perform mesoscale hydrodynamics simulations of spheroidal squirmers and show an enhanced wall and center depletion, and alignment of the propulsion direction parallel to the flow, which they interpret as a preferred downstream swimming for all active stresses,
