OpenFOAM- Low Mach Number - boundary
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.
I think you ought to use buoyantPressure boundary condition for pd.
