  Publication: In this study, we explore how turbulence behaves when two large disks rotate in opposite directions inside a water-filled tank. By adjusting the speed of each disk, we observe how the flow changes from a strong, jet-like stream to a more balanced and symmetric motion. Using advanced imaging techniques, we capture over 50,000 measurements of the flow in each case to understand how chaotic motion evolves under different conditions. These results help scientists better understand how turbulence forms, spreads, and organizes itself in systems ranging from industrial mixers to natural whirlpools. This is especially important when dealing with strong swirling motions and high flow speeds.
