[ESPResSo-users] Brownian motion with lattice Boltzmann

[Salvador H-V]

Dear All,

I have been reading the Thesis of Dominic Røhm where he discuss the implementation of Lattice Boltzmann with GPU's in ESPResSo.

In chapter 8.2, he presents a test case about brownian motion and diffusion of a single particle. 

Some of the parameters used in the simulation were:

density           1.0

viscosity         0.1

friction            5.0

temperature    1.0

I would like to ask for an educated guess of were this parameters come from? Somebody could give me an idea of why these parameters are good enough to reproduce brownian motion and if they could be used in a whole 2D colloidal suspension?

Thanks a lot in advance,

Herrera-Velarde S
