Hi Everyone!
I'm working on a combustion simulation using reactingFoam and the simulation is running ok, I'm seeing the fuel being injected as expected, inlet temperatures and velocities as well... But for some reason, it seems there is no reacting taking place. I would deeply appreciate your advice! Is there anything I'm doing wrong? I'm not sure if I need to update anything on yDefault or anywhere else. For H2 I have a fixedValue of 1 for injection, and O2 I have a fixed value of 0.28 for inlet as well... yDefaul Code:
internalField uniform 0; boundaryField { fuelinlet { type fixedValue; value uniform 0; } airinlet { type fixedValue; value uniform 0; } outlet { type inletOutlet; inletValue uniform 0; value uniform 0; } top { type zeroGradient; } bottom { type zeroGradient; } frontAndBackPlanes { type empty; } } Code:
reactions { un-named-reaction-219 { type reversibleArrheniusReaction; reaction "O2 + 2H2 = 2H2O"; A 38.7; beta 2.7; Ta 3149.977155; } } |

Update:
I'm adding a fvOption to ignite the flame: energySource1 { type scalarSemiImplicitSource; active true; timeStart 0; duration 0.0001; scalarSemiImplicitSourceCoeffs { selectionMode fuelinletCells; volumeMode specific; injectionRateSuSp { h (5e9 0); } } } But now I can't pass the error: "Entry 'cellSet' not found in dictionary" how can I create the defined cellSet for my case? Any recommendation? |
