Simulation of a jet in a supersonic cross-flow

Participant : Pascal Bruel.

In our joint work, published this year with our Kazakh colleagues [10], we have focused on detailing the vortical patterns present in the structure of a sonic jet injected normally into a supersonic crossflow. Such a generic flow configuration is considered to feature some prominent characteristics encountered in propulsion system based on supersonic combustion (scramjet). A critical pressure ratio value beyond which new vortical structures are appearing has been evidenced. Contacts have been taken with ONERA to have access to their experimental database which is much more developed than the one we had access to so far. Some specific adaptation will have to be conducted though, in order to adapt the simulation to the slightly different flow configuration considered by ONERA.
