Abstract

The characteristics of bubble entrainment process owing to a vertical circular jet at the water surface arediscussed. The two-phase flow measurements using imaging technique for two-dimensional bubble measurements, so called Bubble Tracking Velocimetry (BTV) were conducted in the laboratory. The dependence of the air bubble statistics onthe Froude number and salinity beneath the water surface is discussed both downward and rising bubbles. The clear dependence of bubble size distributions on the Froude number is obtained through the experiments.
