I have two questions regarding presenting a reactions in OpenFoam.I tried using OF format as well as chemkin format.
  • In chemkin format I have the issue of representing following compostion.
Code:
C6H6.2O0.2
Is there a way to represent an element composition like C6H6.2O0.2 in chemkin?
  • In OF format I cannot present following reaction and its rate.
Code:
CO + 0.5O2     => CO2
Reaction rate =kr Cco*Co2^0.5*Ch2o^0.5
I tried "thirdBodyIrreversibleArrheniusReactionRate",a nd it did not work.
And I tried to represent reaction in following methods as well.
Code:
CO + 0.5O2+H2O^0.5     => CO2+H2O
&
Code:
CO + 0.5O2 +0H2O^0.5        => CO2
If someone can help me,really appreciate.
Thanks.

Okay.I solved the problem using both chemkin and OpenFOAM reaction files.For anyone who interested.

Code:
foamChemistryFile "$FOAM_CASE/constant/reactions";

foamChemistryThermoFile "$FOAM_CASE/constant/thermo.compressibleGas";

CHEMKINFile     "$FOAM_CASE/chemkin/chem.inp";

CHEMKINThermoFile "$FOAM_CASE/chemkin/therm.dat";
