Microscopic swimmers such as bacteria often show collective behaviours such as spontaneous ordered state at high density and pattern formations at length scales much larger than the size of the swimmer itself. In this talk, I will present a simple phenomenological model of collective swimmers in a regular fluid and how one can solve them numerically using hybrid lattice Boltzmann algorithm. In particular, I will discuss a model of swimmers trapped in a bag/membrane. If time permits, I will also discuss some results from the simulations.
This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
