The numerical simulation of cryogenic combustion is crucial for a better
understanding of the complex physics involved in reactive flows of rocket
engines and to help to reduce the development cost of these engines. The
focus of this study is set on the oxidizer injection and its dispersion through
jet dense core destabilization and atomization or supercritical mixing. Specific
models have been implemented in the CFD code CEDRE created by ONERA to
address these physical phenomena.
