Reinforcement learning of a biflagellate model microswimmer
Sridhar Bulusu, Andreas Zöttl
Many microswimmers are able to swim through viscous fluids by employing periodic non-reciprocal deformations of their appendages. Here we use a simple microswimmer model inspired b…
Dynamics of squirmers in explicitly modeled polymeric fluids
Andreas Zöttl
Biological microswimmers such as bacteria and sperm cells often encounter complex biological fluid environments. Here we use the well-known squirmer microswimmer model to show the…
Mesoscale modelling of polymer aggregate digestion
Javor K. Novev, Amin Doostmohammadi, Andreas Zöttl +1
We use mesoscale simulations to gain insight into the digestion of biopolymers by studying the break-up dynamics of polymer aggregates (boluses) bound by physical cross-links. We i…
Dynamics of individual Brownian rods in a microchannel flow
Andreas Zöttl, Kira E. Klop, Andrew K. Balin +3
We study the orientational dynamics of heavy silica microrods flowing through a microfluidic channel. Comparing experiments and Brownian dynamics simulations we identify different…
Simulating squirmers with multiparticle collision dynamics
Andreas Zöttl, Holger Stark
Multiparticle collision dynamics is a modern coarse-grained simulation technique to treat the hydrodynamics of Newtonian fluids by solving the Navier-Stokes equations. Naturally, i…
Focusing and sorting of ellipsoidal magnetic particles in microchannels
Daiki Matsunaga, Fanlong Meng, Andreas Zoettl +2
We present a simple method to control the position of ellipsoidal magnetic particles in microchannel Poiseuille flow using a static uniform magnetic field. The magnetic field is ut…
