We present two techniques for vortex detection in 2D velocity "elds, based on the macroscopic geometric properties of streamlines. The methods do not depend on the local #ow patterns at a single point used in many other vortex detection techniques. Both methods begin by covering the full domain with a large number of streamlines, and select the curves with circular or looping geometry. The "rst method uses local cumulations of curvature centers which may indicate that many streamlines are… CONTINUE READING
