Statistical properties of a point vortex model for twodimensional turbulence — •Oliver Kamps and Rudolf Friedrich — Institute of Theoretical Physics, Wilhelm-Klemm-Str. 9 48149 Münster

Starting from a point-vortex description of a forced twodimensional flow we investigate the statistical properties of the lagrangian and eulerian fluid dynamics. In our numerical investigations we focus on the probability distribution functions for the velocity increments of the vortex particles. We compare the results with direct numerical simulations of the two dimensional Navier-Stokes equation.
