WebMar 22, 2024 · Introduction. The propulsion systems in most flying and swimming animals (birds, fish, and invertebrates) and bio-inspired platforms (micro air vehicles and unmanned underwater vehicles) employ periodic wing/fin motions that are expected to generate regular periodic fluid loads that aid in locomotion. WebApr 18, 2011 · Abstract. Many microorganisms exhibit taxes, biased swimming motion relative to a directional stimulus. Aggregations of cells with densities dissimilar to the medium in which they swim can induce hydrodynamic instabilities and bioconvection patterns. Here, three novel and mechanistically distinct models of the interaction of the …
