Hello every one, i am modeling the reforming of CH4 to H2 in a reformer, the reaction type is surface reaction and the mechanism is imported from Chemkin files(13 species and 43 reactions). But the reactions seems not occur in my result, can anyone help me find the reason?

first,confirm your chemistry
second, confirm source terms(i.e. volumetric source) third, your mixture properies should be "chemkin~~" others... confirm whether product species exists or not. if product were not, chemical reaction didn't occur.. good luck |

I found the unit in Chemkin file is different from Fluent, i.e. the Arrhenius paramters. when importing the Chemkin file, Fluent automatically change the unit to SI, I found the changed value of the paramters seems not correct, so what's the rules of the change of unit in fluent and chemkin?
