Even though interactions between pulsed jets showed great importance in biological fluid transport, they remain poorly described. An experimental piston/cylinder apparatus is designed to produce twin parallel pulsed jets. Using Particle Image Velocimetry (PIV), we investigate how vortex ring reconnection is influenced by nozzle spacings (S/D_0) varying from 1.49 and 3.20 and stroke ratios (L/D_0) between 2 and 4. Velocity and vorticity visualization suggest there is a critical spacing ratio from which the pulsed jets interact. This value is found to be approximately 3. Below 1.5, the vortex rings are already merged at the jet exit. By implementing a vortex core identification method based on the swirling strength criterion, the reconnection point is then localized. The results highlight how important is the effect of the nozzle spacing compared to the stroke ratio, although the influence of L/D_0 increases with the distance between the jets. Finally, time-frequency analyses confirm the highly fast changes in velocity and vorticity observed during reconnection, and emphasize the importance of the reconnection phase in the newly formed structure.
