Hello,

There is a bug in the kinetic- and diffusion-limited carbon oxidation model (to be used with coalChemistryFoam) solver.
It is in the source file:
OpenFOAM-1.6/src/lagrangian/coalCombustion/submodels/surfaceReactionModel/COxidationKineticDiffusionLimitedRate/COxidationKineticDiffusionLimitedRate.C
The following formula is missing (dt). Thus, it actually calculates dmC/dt (mass-rate of carbon consumption) instead of dmC (increment of carbon consumed over a time step):
scalar dmC = Ap*rhoc*specie::RR*Tc*YO2/WO2_*D0*Rk/(D0 + Rk);
