Hi

I am doing a postgraduate research project involving the combustion process of a liquid propellant rocket engine with triplet impinging jet injectors. I have completed training on multiphase simulations in Ansys Fluent (to model the injection, impingement, primary and secondary atomisation etc). I have also completed a course on combustion modelling in Fluent.

I have come to realize, however, that there are extreme limitations when coupling multiphase and species reactions in Fluent. It does not seem possible to model combustion where both the fuel and oxidizer exist in a liquid droplet form in Fluent.

I understand that this is quite a difficult project, but I am committed to seeing it through to the end (even if the end of me comes first).

My current options are to either:

• Find a workaround for simulating the case in Fluent that I am currently not thinking of.
  
  To investigate other commercial codes which can handle the model requirements (which ideally have an academic license of sorts).
  
  To dive into OpenFoam and see what is feasible.

I figured I would ask the experts (you) if anyone has any experience with such a problem, or has any suggestions for paths I can take.

Thanks for any responses.

Since you mention a triplet injector, I assume you are referring to rocket engines for orbital vehicles and not bottle rockets... Something to keep in mind:

1. Combustion reactions are categorically gas phase reactions. Liquids don't combust. They become gases and then they combust.
2. Liquid propellants aren't liquid at the injector, they're supercritical
