| الوصف: | International audience ; The reliability of rocket engines is one of the priorities given to the Ariane 6 European Space Agency program. A cryogenic combustion chamber faces many physical phenomena, which are interacting with each other and involve a large spectrum of length and time scales. Amongst them, the primary atomization plays a major role and should be investigated to understand its influence on high frequency instabilities developing in the chamber. Such instabilities have been encountered in the recent past and can cause highly destructive damages for cryogenic rocket engines. Whereas experiments are crucial in order to validate simulations and understand the physics of such phenomena, predictive numerical simulation are mandatory, at least as a complementary tool in order to understand the physics as well as to design new combustion chambers and predict their potential of developing instabilities in various configurations. In subcritical conditions, a co-axial injector involves liquid oxygen and di-hydrogen two-phase flow with three distinct topology regions. |
