Zusammenfassung

The locomotion of microorganisms in a fluid - such as E. coli bacteria, which are propelled by bundles composed of several helical flagella - is studied by mesoscale hydrodynamic simulations. The project aims at a detailed understanding of the swimming pattern of these bacteria, in particular, the cooperative behavior of several flagella and its role in directed motion and tumbling. For this purpose, two complementary simulation techniques, Stokesian hydrodynamics and multiparticle collision dynamics (MPC), are exploited to account for fluid flow. The individual strengths of the two a...
