Hi Foamers,
I am currently working on gasification process, and using reactingTwoPhaseEulerFoam solver (in multiphase/reactingEulerFoam) and bubbleColumnEvaporatingReacting as the basis of my case. In bubbleColumnEvaporatingReacting/constant/reactions.gas folder, there are : species ( CO CO2 H2 H2O AIR ); reactions { waterGasShift { type reversibleArrheniusReaction; reaction "CO^0.93 + H2O^0.24 = CO2^0.69 + H2^1"; A 1e8; beta 0.86; Ta 1e4; } } The case I would like to develop consists of 4 main reactions : C(CHAR) + H2O => CO + H2 CO + H2O <=> CO2 + H2 C(CHAR) + CO2 => 2CO C(CHAR) + 2H2 => CH4 I started to modify liquid terms to particle in the tutorial case knowing that in my case I have two phases namely gas and particle dispersed (interpreting as a continuum fluid). And I run my case and it compiled very well. But I do not make change in reactions, phaseProperties and thermophysicalProperties in order to implement my reactions, define my phases or species properties. So my questions are, how can I implement my species and reactions and parametrize thermophysicalProperties and phaseProperties in my case (gas and particle fluid phases)? I see there is thermo.gas file where the gas species in the reactions are defined. But in my case, there is C(CHAR) which is a solid particle not a gas and I would like to know how can I define it, in another file I will create or what? Thanks in advance for your reply Best regards |
