A Lattice-Boltzmann model for suspensions of self-propelling colloidal particles.

S Ramachandran¹, P B Sunil Kumar, I Pagonabarraga.

Abstract

We present a Lattice-Boltzmann method for simulating self-propelling (active) colloidal particles in two dimensions. Active particles with symmetric and asymmetric force distribution on their surface are considered. The velocity field generated by a single active particle, changing its orientation randomly, and the different time scales involved are characterized in detail. The steady-state speed distribution in the fluid, resulting from the activity, is shown to deviate considerably from the equilibrium distribution.
