Applied Math Seminar: Simulations of a 3D Swimming Monotrichous Bacterial Model
3:10 PM, Webster B8
Abstract: The bacterium of the monotrichous type, which has only a single flagellum, is not like the peritrichous type bacterium, such as Escherichia Coli, with more than one flagellum over the cell body. The run and tumble swimming mechanism that the peritrichous type bacterium performed may not appropriate to express the mechanism that the bacteria of monotrichous type proceeded. A model of a 3D bacterium swims under the single flagellate mechanism is built up to investigate the motility of monotrichous bacterium. The immersed boundary method is used to solve the fluid dynamics and will be briefly introduced. Some simulations generated by this model, such as the zero- torque swimming, external fluid dynamics around the cell body and the interaction of two or more bacteria, will be presented in this talk by animation clips.
