Locomotion and Complex Fluids
If you have a question about this talk, please contact jnm11.
A bacterial bath is a fascinating example of an active suspension where the forcing of the fluid microstructure drives larger-scale dynamics in space and time. In joint work with David Saintillan, we have adapted numerical tools for studying rigid rod suspensions to studying the dynamics of suspensions of self-locomoting rods. Through our simulations we demonstrate the instability of large-scale orientational ordering (predicted theoretically by Ramaswamy and Sinha), the persistence of short-range order, study the role of Taylor dispersion in this system, and examine some of the effects of boundary conditions and differing swimmer models. If time permits I will also discuss recent work on the effect of fluid visco-elasticity on the locomotion of an undulatory sheet.
