Plane two-phase (liquid + gas) jets occur in plunging jet bubble columns, and have potential applications in the inertial confinement fusion systems. In this investigation, some basic hydrodynamic and stability characteristics of these jets are studied. An experimental test facility is used where plunging plane two-phase jets are generated using air and water. The jet inlet flow characteristics are systematically varied. The void fraction distribution in the jet is measured at several locations along the jet, using the Gamma-Ray densitometry technique. The jet thickness is also measured. The void distribution profiles are then used for the qualitative assessment of the internal flow and phase interaction phenomena in the jet. The limits of the stability of the jet are also experimentally specified. Theoretical modeling of the macroscopic flow phenomena is also addressed.
