Heterogeneous reaction rate problems

  Good morning,nnI am trying to model a fluidized bed reactor where a heterogeneous reaction occurs between CO2 and iron oxides.nnI went to the phase interaction section of the eulerian multiphase model and then inserted all the parameters required relating to the reaction. As a reaction rate function I selected the Arrhenius one and then I properly inserted the pre-exponential factor, activation energy and so on.nnThen, when I run the simulation I see that no products are formed and it seems that the reaction is actually not occurring. I don't think it is a matter of letting the simulation run, because I tried with arbitrary and very high factors of the Arrhenius law and the behavious remained identical.nnI do not understand where is my issue. Maybe I need to define a mass transfer mechanism with the heterogeneous reaction rate in order to see the formation of the products...nnThank your for your attentionn
