摘要

The transport of gas bubbles in liquid environments is essential across applications like microfluidics, drug delivery, and energy systems, but achieving stable, high-speed motion remains a challenge. We present an advanced implementation of submerged spark discharge-driven ring bubble generation by leveraging the dynamic interactions and fluid motion at high velocities and accelerations generated by high initial overpressure, achieving high-circulation bubbles that reach initial velocities of 12 m/s, travel 800 mm, which also can be generated in extreme stroke ratios and minimal space. Key features include self-contained movement, collision resilience, and adaptability across media. Scalable and programmable, this method enables precision in bubble manipulation, paving the way for advanced applications in fluid transport, environmental engineering, and biomedical systems.
