I have a problem with chem.reaction modeling in Fluent (laminar Finite-rate model)
Boundary conditions: Mixture - 3 species Mass fraction of I0 = 0.001 Mass fraction of R0 = 0 Mass fraction of M = 0.999 Mixture flows into the tube Reactions: I0 -> 2R0 M is not involved into reaction. After calculation, mass fraction of specie I0 become 0, mass fraction of specie R0 become 0.0015, and mass fraction of M become 0.9985 (so, M turns into R0, BUT M should not react and change own mass fraction). I tried to use stiff solver, but result is the same. Any ideas? I can attach files with solution if it's necessary |
