摘要：

This paper presents experimental data on the air entrainment process for a plunging liquid jet. Local data, including the size distribution of the bubble diameter, void fraction, bubble velocities and turbulent liquid velocities were obtained using a fiber optics phase Doppler anemometer system. A dual element conductivity probe was also used to measure the spatial distribution of the local void fraction. For the larger bubbles, the turbulence of the plunging jet was parametrically controlled using a specially designed nozzle and the turbulence intensity was measured using a laser Doppler anemometer system.
