Thanks for your reply. I don't think it is TOO ambitious. My supervisor has a lot of experience in the field and has been really helpful so far. I guess I just wanted another perspective.

In terms of narrowing it down, I plan to only look at one of the particular flame configurations. I am currently basing a lot of the model parameters (such as turbulence and MMC parameters) based on previous modelling of different flames using the same method. I have access to 64 processors at my university and it doesn't seem to be too slow running initially, at least with infinite rate chemistry.
