OPTICAL DIAGNOSTICS OF ATOMIZATION AND COMBUSTION FOR CRYOGENIC LIQUID ROCKET PROPULSION
RÉSUMÉ
The M3 micro-combustor is a test facility for basic investigations of cryogenic oxygen/hydrogen rocket propulsion. 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.
