Hi.
Explain please, what is "asp" ?
Code:
    singleMixtureFractionCoeffs
    {
        phases
        (
            gas
            {
                CH4             0.604;
                H2              0.099;
                CO2             0.297;
            }
            liquid
            {
                H2O             1;
            }
            solid
            {
                ash            0.136304; // What is it?
                C              0.863696;
            }
        );
        YGasTot0        0.211;
        YLiquidTot0     0.026;
        YSolidTot0      0.763;
    }
Also, I do not understand what that is YGasTot0,
YLiquidTot0,YSolidTot0?
"singleMixtureFractionCoeffs" determines how much mass the liquid is in the gas, or solids?

Hello.
Isn't it just 'ash' - the solid remains of combustion?

I thought it was limestone.

Also, I can not understand the coal dust burning in the mix, or just "floating" in the volume. The rectangle of burning coal dust is shown.


species
(
N2
O2
CH4
H2
CO2
H2O
);

reactions
{
methaneReaction
{
type irreversibleArrheniusReaction;
reaction "CH4 + 2O2^1.0 = CO2 + 2H2O^1.0";
A 7e+06;
beta 0;
Ta 10063.8;
}
hydrogenReaction
{
type irreversibleArrheniusReaction;
reaction "H2 + 0.5O2^1.0 = H2O";
A 4.74342e+12;
beta 0;
Ta 10063.8;
}

}

Hello,

I am supposed to work with coalChemistryFoam which is not my main field. Thus, I amjust wondering if you have any material describing the tutorial case in more detail. I am struggling to understand coalCloudProperties and for eample what are the reactions inluded in the model and so on. Many thansk ina dvance.
