Dear OpenFOAM users,
I made my own reaction rate function (in according to hints from this forum) and everything works perfectly. I have total match between manual calculation, DWSIM and OpenFOAM. If somebody will be interested in this in future, little hint -> check units. It is biggest mind****. I created reaction rate as polynomial, dependent on temperature. I would like to add also mass fraction dependence. My reaction rate is created from LangmuirHinshelwoodReactionRate. This reaction rate can use variables: pressure (P), temperature (T) and molar concentration (c). For example in StandardChemistryModel.C i see for molar mass, but I don't know how to define specieThermo_. Code:
scalar W = specieThermo_[i].W() Is there a simple (or relative) way to add mass fraction "Y" to LangmuirHinshelwoodReactionRateI.H ? (or actual "rho"? from "c" it is simple to calculate "Y"...) thanks, BR, ii Last edited by iiigoriii; November 16, 2018 at 16:13. |
