Hi Foamers,
I'm working on a simulation of combustion in porous media with reactingFoam solver. in example methane one step mechanism is as follows ____ species ( O2 H2O CH4 CO2 N2 ); reactions { methaneReaction { type irreversibleArrheniusReaction; reaction "CH4 + 2O2 = CO2 + 2H2O"; A 5.2e16; beta 0; Ta 14906; } } ---- in reactins file in constant folder. But I want to use methane from a 4-step mechanism. reactions Ar b Ts CH4 + 1 O2 → CO + 2H2 7.82 . 1013 0 CH4 + H2 O → CO + 3H2 3.00 · 1011 0 H2 + 1 O2 → H2 O 5.0 · 1020 -1 CO + H2 O ---> CO2 + H2 2.75 · 1012 0 Who knows how to put these reactins? comment: i want to use "chemistryReader foamChemistryReader;"in file thermophysicalProperties. and i know to use in chemkin import( "$FOAM_CASE/chemkin/chem.inp") for multi step reaction but i want to use foam chemistry reader. |
