Hi All!
I need to simulate a two-phase combustion process using CFX.
I already have experience in combustion simulations, but only with two gases.
I do not know exactly which models need to be activated and used if a liquid is injected inside the combustion chamber, then is heated up, becomes a vapor and finally reacts with the gas already present inside the combustion chamber.

Thanks a lot for your help.

Let me know if you need any further clarifications about my application.

Never did that. Guess you have to model the injected full as lagrangian particles. Guess you should model evaporation, which produces the gas phase of the fuel. The rest is the same procedure as before. This approach should be possible for EDM or finite rate. (Also for combination, however I never recommend to use that).
For flamelet it is a challenge. Contact the service for this.
