Combustion model for deflagration-to-detonation
 
Hi!
I am trying to achieve a deflagration-to-detonation in a 3.5 m long pipe which is closed in one end, and I was wondering if any of you have a recommendation to which combustion model I should use. I have tried with the EBU model, with no luck. I'm using atmospheric conditions as inital conditions and a stoichiometric H2/O2 mixture. The time step size is 1E-6.

Which variant of EBU (hybrid, standard, Only kinetics, combined time scale) did you try?

You can try EBU with kinetics only.
