The model combustor is operated at pressures up to 2MPa and has full optical access to study in detail the LOX-spray combustion phenomena with nonintrusive optical diagnostic techniques. Oxygen and hydrogen are injected at 77 K through a single coaxial injection element. The phenomenology of LOX-jet break up and the topology of the flowfield has been investigated by flashlamp and laser light-sheet photography to determine the distribution of the liquid phase and by droplet tracking to measure the droplets velocities. Location and structure of the flamefront has been investigated by laser-induced fluorescence and the detection of the spontaneous emission of the OH radical. %8 1997-01-01
