Hi all,

Our work is based on the fact that, under the VOF framework, the flow of the isothermal mixture belongs to the variable-density incompressible flow category. For such flows, VOF-based solvers of OpenFOAM fail to construct the correct governing equations for turbulence modeling. varRhoTurbVOF contains a set of newly designed VOF-based solvers which could use the desired governing equations for turbulence quantities.

The paper which explains the issue and solution in detail is available at
https://doi.org/10.1016/j.cpc.2019.106876
and
https://arxiv.org/abs/1811.12580v2

Implementations for various OpenFOAM versions are provided at
https://github.com/wenyuan-fan/varRhoTurbVOF​

I have already reported this to both ESI Group and OpenFOAM Foundation, details and updates could be found at
https://develop.openfoam.com/Develop...us/issues/1433
and
https://bugs.openfoam.org/view.php?id=3344

I hope the community could test the new solvers on a wide range of cases and give feedback.

Best regards,
Wenyuan
