Hello, everyone.
I have such a question as follow:
I want to simulate gas-solid reaction and I need to set chemical reaction between these two phase. We all know, FLUENT provide us with three kinds of reaction: Volumetric, Wall, Surface particle. And my reaction is exactly that a lot of solid particles reacts with gas. But I have read Theroy Guide and I found that the surface particle reaction seems to be the one that the products are all gas like combusition. But in my example, the products are not all gas, one of them is solid and it surround the reactants.
If I could choose surface particle reaction to simulate my reaction?
Expect for your advice! Thank you all!
