velocityGroup Class Reference

Computes the Sauter mean diameter based on a user specified size distribution, defined in terms of size class fractions. Intended for use with a population balance model to account for the evolution of a size distribution by means of coalescence, breakup, drift and nucleation. More...

Detailed Description

Computes the Sauter mean diameter based on a user specified size distribution, defined in terms of size class fractions. Intended for use with a population balance model to account for the evolution of a size distribution by means of coalescence, breakup, drift and nucleation.

Usage

Excerpt from an examplary phaseProperties dictionary:

diameterModel   velocityGroup;

velocityGroupCoeffs
{
    populationBalance    bubbles;

    shapeModel           spherical;

    sizeGroups
    (
        f1 {dSph  1e-3; value 1.0;}
        f2 {dSph  2e-3; value 0.0;}
        f3 {dSph  3e-3; value 0.0;}
        f4 {dSph  4e-3; value 0.0;}
        f5 {dSph  5e-3; value 0.0;}
        ...
    );
}
