How to model a reversible reaction with a solid catalyst in ANSYS Fluent?

Ahmed Saeed Mansour · April 11, 2021, 10:33

Hello, I have a reversible reaction and a solid catalyst is used. In Fluent I see volumetric reaction and I can select backward reaction to define the reversible behavior. However, I am not able to define the catalyst unless I make it particle surface reaction not volumetric.
How can I define the catalyst + the backward reaction?
Thank you!

If you intend to use the particle surface model you need to define your solid particles via the discrete phase model.
