Lattice Boltzmann Methods for Active Fluids

Lattice Boltzmann Methods for Active Fluids - Livio Carenza, Department of Physics, University of Bari (Italy)
Abstract: Active Matter is a peculiar kind of Soft Matter whose constituents are able to inject energy in the system at the level of the individual constituents, so that active systems evolve inherently far from thermodynamic equilibrium.
In this presentation I will provide an overview of continuum approaches suitable to model active matter in fluid environments, starting from a coarse-grained description of the active constituents and their active effect on the surrounding fluid. I will provide an overview of the basic features of Lattice Boltzmann, the numerical method implemented to integrate dynamical equations of active matter and present some details regarding the parallelization of the code used for simulations.
Furthermore I will provide an overview of some interesting phenomena arising in active matter, ranging from Spontaneous Flow to Active Turbulence.
