Hi Friends
I have a solver for simulation low mach flow. I have some question about boundary condition. I want to simulate flame propagation in open tube. which boundary condition must I use for pd? I used zeroGradient for walls and inlet and fixValue(=1 atm) for outlet. but this boundary condition calculate pd about 1 atm whereas pd must be little than pReff. (pd<<pReff) and i thinck this is wrong. thanks alot |

I think you ought to use buoyantPressure boundary condition for pd.
