Dear Foamers,
i'm trying to use fireFoam to simulate an ethanol small Pool evaporation and dispersion. Already figered out how to disable combustion. But got stucked on how to change, add, species on this tutorial. Any direction would be very welcome. I''m running OpenFOAM v2212 on linux ubuntu 22.04. Thanks in advance. |

Hello.
There is a lack of tutorials for fireFoam solver. But how to change, add species one can find out at reactingFoam tutorial. This is a similar solver and its tutorial is well known and can be simply downloaded here at the forum. |

Oh, thanks Roman.
I wonder if there are tutorial of the rhoReactingBuoyantFoam My reactions file: species ( O2 H2O C2H5OH CO2 N2 ); reactions { methaneReaction { type irreversibleinfiniteReaction; reaction "C2H5OH + 3O2 + 11.25N2 = 2CO2 + 3H2O + 11.25N2";//"CH4 + 2O2 + 7.5N2 = CO2 + 2H2O + 7.5N2"; } } reactions.two_Steps species ( O2 H2O C2H5OH CO2 CO N2 ); reactions { methaneReaction { type irreversibleArrheniusReaction; reaction "CH4^0.9 + 2O2^1.1 = CO + 2H2O"; A 2.119e12; beta 0; Ta 17676; } COReaction { type irreversibleArrheniusReaction; reaction "CO + 0.5O2^0.25 = CO2"; A 1e6; beta 0; Ta 6060; } } I wonder where can i find reaction and those coefficients for C2H5OH Last edited by brunobw; December 14, 2023 at 16:19. |
