combustion chamber 3D Simulation
 
Hi,
I`ve had problems with my CC (combustion chamber) 3D simulation.
the geometry of the CC is a normal anular CC geometry (a Casing and a flame tube holes ) with a Hydrogen-air Mixture combustion.
I created the mesh in gambit and when i import it to Fluent everything is ok, i activate the energy equation, the K epsilon model, and the species transpor too, the boundary conditios have 2 Velocity inlets (fuel and air), a radiator, Holes in the flame tube, and the Outflow, and finally in solution initialization i set: inicialize from all zones, but after of 400 or 600 iteraions, the simulation CONVERGE and the results determine that the flame is over, so the CC doesn`t have combustion.
What Kind of problems could i be having ?????

thank for your Help.
