Pressure waves radiated by radial oscillating large spark generated bubbles have been recorded and analyzed. The first maximum radii of the generated bubbles range from 21 to 58 mm. It is shown that for bubbles of this size damping of radial oscillations increases with the bubble size. Explanation for this effect is suggested in the upward bubble motion.

Abstract
Pressure waves radiated by radial oscillating large spark generated bubbles have been recorded and analyzed. The first maximum radii of the generated bubbles range from 21 to 58 mm. It is shown that for bubbles of this size damping of radial oscillations increases with the bubble size. Explanation for this effect is suggested in the upward bubble motion.File in questo prodotto:
