How to inject gas into supersonic flow?

Dear All,
First of all, I'm sorry for the poor sentences because I don't speak English as my mother tongue. And my first post. I'd like to simulate the phenomenon that inject gas into supersonic flow as shown in attached image. This is a simulation injection at pressure ratios of 15 and 20 into M2.9 flow using sonicFoam. Flow field and injection gas are same ideal gases. However, I searched for a way to change the type of gas that erupted, but could not find it. Please let me know if you have any good ideas. I'm also thinking about using twoPhaseEulerFoam for this problem, and I'm working on it, but I get the following error and can't simulate. Code:
--> FOAM FATAL ERROR: (openfoam-2012) Requested dispersed phase from an unordered pair. From virtual const Foam::phaseModel& Foam::phasePair::dispersed() const in file phasePair/phasePair.C at line 87. FOAM exiting Is this impossible? Thank you. |

I think that sonicFoam is not applicable for two phases.
Have a look here for suggestions of solvers, e.g. rhoReactingFoam? Gas injection in another gas |

Hi David,
Thank you for your reply. I overlooked rRF solver because there was no its tutorial in v2012. I'll give it a try. Thank you! Satium |
