Abstract
We study the robustness of the vortex street behind a circular cylinde
r when there is transfer of momentum between the wake and the surround
ing fluid. The model used to represent exchanges of momentum is based
on Levy walks, as implemented in lattice-gas hydrodynamics. We show th
at the transverse velocity, considered as a function of the maximum le
ngth of exchanges, is a good order parameter for describing how the co
herence of the vortex street is affected by transport of fluid in and
out of it.
