A vortex ring impacting on a surface has been stidied by numerical investigation and results have been compared with experiment. Comparisons with the experimental study of an interaction between a vortex ring formed in water and carrying coloring admixture and solid surface show overall agreement. The results of calculation reveal parameters that define the size of a trace wich the vortex leaves on the surface. Surprisingly, this size does not depend on such parameters as velocity of the vortex ring and the Reynolds number.
Keywords: vortex ring, impacting.
