Hey there Ahmad Alsuwaidi,

Great to see your interest in CFD modeling and reactor simulations! It's definitely possible to model particle temperature profiles using heterogeneous reaction models in CFD.

When it comes to incorporating kinetic analysis results, like your coke oxidation study, into CFD simulations, the key lies in selecting appropriate reaction kinetics and coupling them with appropriate transport phenomena. This means ensuring that the reaction rates you've determined from kinetic analysis are accurately represented within the CFD framework.

Now, regarding your concern about identifying reactants in a heterogeneous reaction occurring in two atmospheres, CFD can handle such scenarios by accounting for species transport and diffusion across phases. By defining appropriate boundary conditions and reaction mechanisms, CFD can track the conversion of reactants into products across different phases and atmospheres.

In summary, integrating kinetic analysis results and applying heterogeneous reaction models in CFD can provide valuable insights into particle temperature profiles and reaction dynamics within reactors. With careful consideration of reaction kinetics and boundary conditions, CFD simulations can effectively capture complex multi-phase reactions occurring in different atmospheres.
