How can I implement multistep reactions in CFX?
I found some reduced multiple-step reactions for methane-air mixture. And I want to import it into CFX. But I do not know how can I achieve it.
Does anyone can help me? Thanks-Harry |

Dear Harry,
Have you looked at how ANSYS CFX does the multiple step reactions? Try using one of the provided mechanisms work, and copy/paste from there. Opaque |

Thanks, Opaque
I find several reaction mechanisms in CFX installation folder. Without NO formation, there are: Methane Air WD1--one step; Methane Air WD2--two steps; Methane Air WGS--five steps; Methane Air FLL STP Right? Is there any limitation when using them? If I have a reaction model, with several species and several reactions, how can I use it in CFX? Thank you! |

Dear Harry,
There is no chemical reaction import mechanism in CFX; therefore, you must type the CCL using the supplied mechanism as a template. Look into your CFX installation directory for the file etc/reactions-extra/REACTIONS-standard.ccl The syntax of how to write your own mechanism is described. Opaque |
