Particle Surface Reaction
 

Hello.

I'm trying to model the following reaction: 4 Al (s) + 3 O2 (g) --> 2 Al2O3 (s)

I have a fully converged flow field composed by oxygen and I want to introduce the aluminium particles, and then compute the oxidation.

However, I can't get how to set my model since I can't define the reaction with the particle materials, neither define the particle material as one of my mixture components.

How can I model this? Anyone tried this out?

Thank you.
