A two-dimensional air impinging jet with a passive control has been studied experimentally, and smoke visualization, measurement of mean flow characteristics, and mass transfer experiments have been performed. Flow field is intrinsically bistable, and two flow patterns exist under the same boundary conditions. The both patterns differ in a bubble of separated flow, either a small or large recirculation area is embraced inside the jet. A change between flow field patterns is hysteretic in character.
