Visualization on Aerated Bubbles in the Surf Zone

The two-phase flow measurements using imaging technique for two-dimensional bubble measurements, so called Bubble Tracking Velocimetry (BTV) and PIV were conducted to the surf zone breaking waves. The characteristics of air bubbles in the surf zone such as bubble distributions, bubble size spectra,...

Summary:The two-phase flow measurements using imaging technique for two-dimensional bubble measurements, so called Bubble Tracking Velocimetry (BTV) and PIV were conducted to the surf zone breaking waves. The characteristics of air bubbles in the surf zone such as bubble distributions, bubble size spectra, and turbulent characteristics of fluid velocity were measured with highly temporal and spatial resolutions in the laboratory. The temporal transitions of bubble size spectra were measured and the relationship between the gas and liquid phases were analyzed for the surf zone breaking waves.
