Dear all,
I'm trying to simulate H2/O2 catalytic reaction on Pt. I'm using Fluent coupled with Chemkin to do that. I can do it just fine and I get reasonable results. But when I want to compare it against the experiments, I need to take the experimentally measured active catalyst sites into account. It's done by multiplying an F factor to the calculated rate of reaction at the boundaries with a catalyst. Since I don't have access to the boundary equations and species equations, what is the best way to add the experiment/geometry ratio factor? I was thinking of multiplying the rate constant by the factor to increase/reduce the rate of the reactions. Thanks a lot |

If you mean to set the value for specific active area in surface reaction which has a unit (1/m), then you can access it from Cell zone condition/ (interest zone)/ reaction/ surface to volume ratio (1/m) Hope it helps
