Detailed Description

Applies corrections to the turbulent kinetic energy equation (i.e. k) and turbulent viscosity field (i.e. nut) for incompressible multiphase flow cases.

Turbulent kinetic energy is over-predicted in VOF solvers at the phase interface and throughout the water column in nearly-potential flow regions beneath surface waves.

Sources applied to:

  k         | Turbulent kinetic energy                   [m2/s2]
  nut       | Turbulent viscosity                        [m/s2]

Required fields:

  epsilon   | Turbulent kinetic energy dissipation rate  [m2/s3]
  k         | Turbulent kinetic energy                   [m2/s2]
  nut       | Turbulent viscosity                        [m/s2]
Usage
Minimal example by using constant/fvOptions:
multiphaseStabilizedTurbulence1
{
    // Mandatory entries (unmodifiable)
    type                 multiphaseStabilizedTurbulence;

    // Optional entries (unmodifiable)
    rho             <rhoName>;
    Cmu             0.09;  // from k-epsilon model
    C               1.51;  // from k-omega model
    lambda2         0.1;   // A value of 0 sets the nut correction to 0
    alpha           1.36;  // 1/Prt

    // Mandatory/Optional (inherited) entries
    ...
}

where the entries mean:

Property Description Type Reqd Dflt
type Type name: multiphaseStabilizedTurbulence word yes -
rho Name of operand density field word yes rho
Cmu Model coefficient scalar no 0.09
C Model coefficient scalar no 1.51
lambda2 Ratio of nut correction scalar no 0.1
alpha Inverse of turbulent Prandtl number scalar no 1.36

The inherited entries are elaborated in:

Note
  • The model C coefficient for the k-epsilon model equates to C2/C1 = 1.33; the (default) value of 1.51 comes from the k-omega model and is more conservative.
  • Only applicable to epsilon-based turbulence closure models.
