Abstract
We show how in the Lévy-walk model for turbulent channel flow one can measure an effective viscosity in a two-dimensional lattice-gas implementation. We study the dependence of effective viscosity on the exponent characterizing the distribution of distances over which momentum is exchanged and on system size.
