Hello,

I am using the Eulerian multiphase model for two phase flow problems with RANS. It is well known that RANS governing equations are averaged. However, I am not sure what kind of averaging, i.e. conventional averaging or density weighted (Favre) averaging, is used in Eulerian multiphase model in Fluent.

I think it is very likely that the Favre averaging is used for this model in Fluent. So the problem is, which density is used as the weighting factor? We have three densities in this model, i.e. bulk primary (gas) density, bulk secondary (particle or droplet phase) density and mixture density. Does anybody know which one is used in Eulerian model for Fluent?

Thank you so much.
