An experimental study was conducted on head-on collisions of Re = 2000 and 4000 vortex rings upon air-water interfaces to study the vortex dynamics and the effects of different vortex ring Reynolds numbers on the key vortex flow mechanisms. Unfiltered tap water was used where surface contaminants we...
