Formation of a drop size distribution in a gas-liquid stream

Holography was used to study the formation of drop size distribution in dispersive annular gas-liquid flows; experiments were performed using water, ethyl alcohol, and glycerine solution. Attention was paid to the deformation of the wave-surface of the liquid film on the wall (of the test channel) with consideration of critical deformations leading to destruction of the film. The size distribution of primary drops formed during the destruction of the wave, and the behavior of drops detached in the gas flow were also studied. It is found that the drop size distribution in the core of the gas flow is determined by the fragmentation of the liquid film detached from the wall in the gaseous boundary layer.
