Default Modeling a reactive two-phase flow
Posts: n/a
Hi all. I have a problem: I must model a reacting two-phase flow (air(g) surrounded by heptane(l)). It is liquid-gas stratified (no droplets or spray). Unfortunately it seems like VOF, Mixture and Eulerian Models cannot be used for such a problem because they don't handle species mixing and reacting flows.

Are there other fluent's models which can support stratified 2-phase and combustion? Does anyone have any suggestion?

Thank you. Luca

Ciao Luca,

from what I know, the only way VOF can handle chemistry is by UDF, defining an heterogeneous reaction rate between phases. Mass transfers are also possible.

Hope someone will be more helpful...

Good luck

Thank you very much!

So I think I have two possibilities: 1- modeling the two-phase flow by UDFs and exploiting a fluent combustion model

2- vice versa. But I guess the first case is easier.
