Hello,

I have recently started using OpenFOAM. Specifically, I am trying to model a multiphase/multicomponent bubble column-like problem. It seems to me that the multiphaseEulerFoam solver is perfectly suitable for this task. However, I have a couple of questions.

First, for the calculation of the interphase interactions, the Eulerian model assumes that each phase forms bubbles of a constant diameter. In the absence of any experimental data, is there any empirical model that we can use to calculate this diameter?

My second question regards the compressibility of each phase. The documentation states that the solver is for compressible fluid phases (http://cfd.direct/openfoam/user-guide/standard-solvers/). Glancing at the code however, I can see that the energy (or temperature) equation is not solved. Am I missing something?

Finally, commercial software packages often consider a multiphase model called the mixture model (or at least that is what ANSYS is calling it). This is much more efficient than its Eulerian counterpart and might be suitable for my case. Does OpenFOAM have something equivalent?

Thanks in advance for any help
