Dear OpenFOAM Community,
As a long-time user but first-time developer of OpenFOAM, I am reaching out for clarification regarding the best choice of a multiphase solver for simulating flow in porous media using mixture theory, i.e. mass and momentum are solved for a mixture of phases. A bit of background about myself: I have extensive experience in computational fluid dynamics (CFD), primarily working in the field of incompressible large-eddy simulation (LES) for aerodynamics. However, I am relatively new to the field of multiphase flows and porous media in OpenFOAM. I am starting a project which mainly focuses on the development of a multiphase flow solver based on mixture theory. The focus is on understanding the interaction between multiple phases and a porous medium (which ideally would be simulated as a solid phase), with potential applications including:
I am aware that driftFluxFoam uses the mixture approach, but it seems to be limited to interactions between sludge/water or dispersed phase/water. Additionally, I am uncertain about its accuracy when it comes to simulating air/water, vapor/water interactions, or interactions with porous structures. I have also found targeted solvers such as porousMedia4Foam and porousMuliphaseFoam but, as far as I understood, they make use of Darcy-Brinkman approach and I would like to stay with the full NS equations. If anyone has experience or insights regarding this, I would greatly appreciate any recommendations, suggestions, or pointers to relevant resources. Thank you all in advance for your assistance and valuable input. Best regards, G |
