摘要：
An experimental procedure for performing simultaneous, phase-separated measurements in a bubbly, two-phase flow is described and demonstrated with the application to a system of bubbles rising in water. PIV measurements using a vertical laser light sheet are combined with the simultaneous recording of the bubbles' motion by means of a digital high-speed camera viewing the bubbles from above. This experimental approach is aimed at providing a means for characterizing the “pseudo-turbulence” induced by the bubbles in the liquid phase.
