This leads to wave-like effects, such as interferences, the formation of solitons, and a velocity field that is locally curl-free, implying that vorticity is carried by singularities associated with vortices. Using analytical derivations and numerical simulations in 2D, we study the evolution of such a system from stochastic initial conditions with nonzero angular momentum.
