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.
