Mass exchange between the atmosphere of turbulent vortex ring and the surrounding medium is investigated in the initial stage of motion using the shadow visualization method. For this purpose, vortex rings in which the liquid has a different density as compared with the density of the surrounding medium are generated. The experiments are carried out for various values of the density differences, the velocities, and the vortex sizes. The characteristic time and space scales of mass exchange are determined. It is concluded that the basic mechanism of mass exchange is turbulent diffusion. The turbulent diffusion coefficient in the atmosphere of vortex ring is estimated using the characteristic time of mass exchange.
