Abstract
An experimental study has been performed to improve the understanding of the initial air–liquid interaction in the near field of an air-blasted breaking water sheet. For the first time, planar laser-induced fluorescence (PLIF) has been used to visualize the air-flow field, seeding the air streams with acetone vapor. Mie scattering from the liquid sheet, together with the acetone fluorescence signal has enabled simultaneous determination of the instantaneous water sheet location and the air-flow structures. The two-phase flow visualization has revealed detachment of the air boundary layer over the air–water interface behind the zones of strong curvature. The pressure field induced by these vortices has been identified as a cause of the enhanced sheet flapping and the instability growth.
