Detailed Description

Free-surface phase turbulence damping function.

Adds an extra source term to the mixture or phase epsilon or omega equation to reduce turbulence generated near a free-surface. The implementation is based on

    & Komen, E. M. J. (2018).

but with an improved formulation for the coefficient A appropriate for unstructured meshes including those with split-cell refinement patterns. However the dimensioned length-scale coefficient delta remains and must be set appropriately for the case by performing test runs and comparing with known results. Clearly this model is far from general and more research is needed in order that delta can be obtained directly from the interface flow and turbulence conditions.

Usage

Example usage:

interfaceTurbulenceDamping
{
    type    interfaceTurbulenceDamping;

    libs    ("libmultiphaseEulerFvModels.so");

    phase   water;

    // Interface turbulence damping length scale
    // This is a required input as described in section 3.3 of the paper
    delta   1e-4;
}
