Investigation of cryogenic propellant flames using computerized tomography of emission images

Résumé

Abstract: Cryogenic propellant combustion is investigated in this paper. It is shown that the mean flame structure may be obtained by applying computerized tomography principles to oxygen-hydrogen (OH) emission images obtained from experiments on a shear coaxial injector. The data correspond to injection conditions typical of those found in rocket motors, but to lower operating pressures of 1, 5, and 10 bar. The transformed emission images yield the mean volumetric OH emission distribution. This quantity may be roughly interpreted as the mean volumetric rate of reaction. The data provide the location of the mean flame zone and confirm that stabilization takes place in the immediate vicinity of the injection plane.
