hello Everyone,
if I want to study, coal combustion in different atmospheres for example in O2/N2 and O2/CO2. I obtain the kinetics of both atmospheres using Hetrogenous models. ( Shrinking core model ) and Random pore model.
I was wondering if it’s possible in CFD to study particle profile. Does the heat transfer affect in CFD will calculated based on the Gas composition input or I should add something in UDF file.
FYI, the reaction models are based on conversion so I am not really sure how CFD will identify the differences in Atmospheres.
further, I wish If I found a sample UDF file that been used for Hetrogensous models.

In general, yes, CFD computations can include particle profiles. The most direct and possibly accurate sources are likely the vendors of the major CFD systems themselves. They may have useful models already, or be willing to help you set up your system, or even take it on for development if they don't have it already in their portfolio of applications.
