averageSlipVel

Syntax

Defined in couplingProperties dictionary.

postProcessingModels
(
    averageSlipVel
);
averageSlipVelProps
{
    useEulerianParticleData no;
    rhoParticle             1500.;
    outputDirName           "averageProps";
    voidfractionFieldName   "voidfraction";
    fluidVelFieldName       "U";
    particleVelFieldName    "Us";
};

  • useEulerianParticleData = switch to activate the usage of eulerian particle data (NOT recommended in case smoothing is used!)

  • rhoParticle = particle density

  • outputDirName = name of the directory to save files

  • voidfractionFieldName = name of the finite volume vector field of the voidage (default: “voidfraction”)

  • fluidVelFieldName = name of the finite volume vector field of the fluid

  • particleVelFieldName = name of the finite volume vector field of the particles

Examples

postProcessingModels
(
    averageSlipVel
);
averageSlipVelProps
{
    useEulerianParticleData no;
    rhoParticle             1500.;
    outputDirName           "averageProps";
    voidfractionFieldName   "voidfraction";
    fluidVelFieldName       "U";
    particleVelFieldName    "Us";
}

Description

The overall average slip velocity avg(U) - avg(Us) (and other average statistics) are calculated and written to a file.

Restrictions

Currently all fields have the same threshold value!
