 note = {When two vortex rings are arranged side by side coplanerly, they approach each other and join to one large ring due to their interaction. This process was numerically simulated using three dimensional vortex filament method. One vortex ring which has vorticity within the core was approximated by a bundle of seven vortex filament rings. Each pair of filaments were crosslinked in turn until a large vortex ring formed., 資料番号: SA0033584000},
