To study the hydrodynamics of a two-phase flow over a submerged perforated sheet (SPS) and the entrainment of water droplets from the water-air interface, a “Bubbler” installation was built. The main observation tool was video recording of the process followed by data analysis. An SPS with two holes was used. Three experiments were performed with different air flow rates. A general picture of air flow was established: the rise of bubbles in the water volume under the SPS, the formation of an air blanket, air bubbling in the layer of water above the SPS, the formation and jump of water drops upward. For each air flow rate, the size of the bubbles in the two-phase layer and the size of the resulting droplets were determined. It was found that with increasing air flow, these parameters increase.
