  How to calculate mass fractions for individual species at the boundaries which are involved in multi-step reactions, especially in species transport?

  Are you using wit CFX or Fluent or other solver? Generally the codes would discretize and solve convective-diffusive transport equations for mass fractions so that we do just need to know the values for the mass fractions / moles fraction at domain boundaries. Which information do you have and what do you want to do?

  I'm using Fluent. I've the stoichiometric coefficients in the 2 step reaction mechanism. I've the initial temperature of the reactants at the inlet. What else do we need to calculate the mass fractions?
