Decomposition reaction
 

Hi,

I would like to model chemical reaction and subseqent diffusion of co2 for a limestone particle in FLUENT. I could define the partcle as a lime stone. But I am not sure how to define a decomposition reaction for the same.

I activated the species transport under species model panel. Under mixture material drop down, I can not see limestone as one of the material. Here i can see only combusion mixture materials.


Could some one can advice me, how I can progress on this???
