Hi Luc,
The main focus of Fluidity's multiphase flow model has been dispersed multiphase flows. However, it is possible to run simulations without specifying a particle diameter and any interaction terms. An example test case is tests/mphase_sedimentation_2d
which considers the settling out of two phases which are initially perfectly mixed (i.e. volume fraction of phase 1 = volume fraction of phase 2 = 0.5). See also tests/mphase_three_layers
which considers 3 phases.
Chapter 4 of my thesis may be of interest if you are planning to use the model: http://hdl.handle.net/10044/1/12785

Hello,
I am a new fluidity user for two-phase flow modelling. Ideally, I would like to use an Eulerian-Eulerian approach where each field has its own set of equations instead of a VOF approach where one set is used for both phases. I wish both phases to be continuous, however, fluidity seems to only allow for 1 continuous phase and 1 dispersed phase only (with a particle diameter to define).
I have tried to run two-phase simulations removing the _ branch and <material_phase/multiphaseproperties> (where the particle diameter is defined) but it was unsuccessful.
So I am wondering if this kind of two-continuous-phase flow simulation is feasible without using the Multimaterial approach.
Many thanks for your help,
Best wishes, Luc B
