The problem of the noise radiated by the inviscid, unsteady (regular and chaotic) motion of arrays of vortices over a flat slip boundary is considered. A two-dimensional vortex-element method, with smoothed vortex elements of spherical overlapping cores, is used to simulate numerically the evolution of the vorticity field.
