Ansys/Fluent/Multiphase

Hello All,

I am using the Eulerian-Eulerian two-fluid model (in Ansys Fluent) to simulate the solid-liquid two-phase flow in a horizontal pipe.
This is the reference paper I am trying to reproduce:
Eulerian-Eulerian Simulation of Particle-Liquid Slurry Flow in Horizontal Pipe
Titus Ntow Ofei and Aidil Yunus Ismail

In "Multiphase Model - Phase Interaction - Interfacial area", it has the following models:
ia-particle
ia-gradient
ia-symmetric
ia-ishii
UDF

On this topic, the reference I found is here:
https://www.afs.enea.it/project/nept...terfacial-area
It talks about the Hibiki-Ishii model and the Ishii-Kim model, which I think is specific to bubbly flows in liquid, which is not my case here.

So I am wondering what are the models here?

Thanks!

The link you are referring to and the models you are talking about are completely different from each other. For a slurry, use ia-particle.

Hello vinerm,

Thanks for your reply!
I am wondering whether you can direct me to the right place to know more about the Interfacial Area models in my case.

These are algebraic equations and are available at

hello, I have same question which of the menu I should choose but my case is multiphase air water in centrifugal pump
