What is the difference between multiphase mixture models of CFX and Fluent?

Dear all,

Hello. Hope all are well. Ca anyone tell me are the mixture models in CFX and Fluent the same? If not, what are the differences? Moreover, Are they one-way or fully coupled? Thanks.

I will let you check the documentation to find the differences. Also be careful about what you mean by mixture model - they might mean different things in different codes.

Thanks a lot. I explored the documentation as advised. I have found similarities between algebraic slip model in CFX and mixture model in Fluent. Are they the same? Thanks.

Algebraic slip model in CFX = mixture model in Fluent

Mixture model in CFX refers to the special case for the interfacial area density (IAD); Fluent calls the IAD an interfacial area concentration (IAC). Fluent's version of the mixture model IAD is the Symmetric Model IAC!

Confused??
