Zusammenfassung

In this project, the locomotion of microorganisms in a fluid is studied by mesoscale hydrodynamic simulations. Specifically, E. coli bacteria are considered, which are propelled by bundles composed of several helical flagella. The authors strive for a detailed understanding of the bacterial swimming pattern, in particular, the cooperative behavior of several flagella and its role in directed motion and tumbling. For this purpose, an elastic model for the flagellum will be constructed. Two alternative simulation techniques, Stokesian hydrodynamics and multiparticle collision dynamics (M...
