Combustion of sprays from triplet injector with green propellants: ethyl alcohol and hydrogen peroxide

Résumé

PPRIME and CNES are investigating the combustion of green storable propellants without catalyst, using jet-impingement injectors to characterize their atomization and combustion. In the present study, triplet injectors are introduced for expecting shorter mixing length. Spray imaging, droplet sizing and combustion visualization are performed on triplet injectors. Triplet combustion performance is finally compared to that of doublet injectors in terms of characteristic velocity efficiency.
