Catalytic reaction solve by FLUENT
 

Hello,

I want to do simulation on catalytic reaction. I am using ethanol-air mixture at a velocity 30 m/s. It goes through porous catalytic media where flow inside the media is laminar. Reaction occurs inside the media. As a model, I am using Species transport and in reaction I checked both volumetric and particle surface. But number of solid species showing "0". How can I solve it? Also what method I should choose? "Laminar Finite-rate" or "Finite-Rate/Eddy-Dissipation" ?
