Hi everybody
I wanna simulate a gas-solid heterogeneous reaction in Ansys Fluent. My aim ist to simulate a gas flow through porous media where a chemical reaction takes place. Its a chemical transformation by gas-Phase infiltration.
The reaction is : SiO(g) +2C(s)SiC (s) +CO(g). The gas phase coming through the inlet is SiO and I get the 2C from a solid porous component. Im totally new in doing chemical reactions so I have some questions, please help :

-What is my site species? Is it C from the porous substrate? Is the deposition of SiC my solid species?

-Which information about the species do I have to enter in Fluent (enthalpy?...)

-When do I need a UDF for the reaction rates?

-Is it even possible to simulate the creation of a solid and a gas as products?

Thanks in advance.
Please contact me for further information or if you can share or want to share your experience with me.
Greetings from Germany.

Did you get the UDF?
