OK, with a 15mm domain size, how long would the flame take to cross the model? Flame speeds vary, but tend to be order of magnitude of m/s  Note, I am not a combustion modelling expert (I have a colleague who is), but I am reasonably experienced in combustion chemistry. If you lit a stochiometric mixture of air & methane/kerosine vapour/whatever in a 15mm long tube would you expect the experimental instruments to measure anything useful? Or would it be over very quickly?Â
