Supersonic Combustion

November 13, 2003, 17:59

I am attempting to run a very simple combustion chamber at supersonic speeds. I am using non-premixed PDF to simulate what I am trying to do. I can run subsonic, no problems, and I can run cold at supersonic speeds as I can use the coupled solver when no PDF is picked.

However when I want to use PDF I have to use a segregated solver, and my results keep diverging no matter what values of relaxation I choose.

Does anyone have any knowledge on simulating combustion at supersonic speeds. Is a non-premixed model the best model to use? And what other models are there that would accurately simulate my problem?

Thank you

Andrew
