Study of Bubble Size Distribution for Breaking Wave Propagates over a Submerged Dike

摘要

Breaking wave plays an important role in air-sea, wave-wave, wave-current, currentcurrent interaction. Wave breaking not only disturbs communication of sound chiefly because of the transient noise of the air-entrained bubbles. A useful analytical method, Gabor transformation, is applied due to its advantages over nonsymmetric and abrupt transition signals in breaking events. Numbers of bubbles and size distribution in a specific wave condition is analyzed in laboratory experiments.
