Abstract

The two-phase flow measurements using dual-tip void probe for bubble size and its moving speed measurements wereconducted for the surf zone breaking waves. The characteristics of air bubbles in the surf zone as void fraction, bubblenumber distributions, bubble size spectra, and turbulent characteristics of fluid velocity were measured with highly temporaland spatial resolutions in the wave flume. The horizontal and vertical distributions of void fraction and characteristicbubble size were measured and modeled empirically. The relationship between the void fraction and wave energydissipation are proposed for the surf zone breaking waves.
