Interaction of vortex filaments at high Reynolds number is visualized using a schlieren method. 1) Several vortex rings are ejected in series along the same axis into still air through a circular orifice and the interactions of them are analyzed. 2) Two vortex rings are ejected simultaneously from two identical circular orifices separated a certain distance and their merging, splitting and interchanging are observed. These interaction phenomena are compared with the numerical results using the discrete vortex method.
