This function object calculates and outputs volume-averaged information about the size distribution of the dispersed phase, such as the number density function or its moments. It is designed to be used exclusively with the population balance modeling functionality of the reactingEulerFoam solvers. It can be applied to a specific cellZone or the entire domain. The function type determines whether the density function and its moments are based on the number of dispersed phase elements in a size group or their total volume. More...

Detailed Description

This function object calculates and outputs volume-averaged information about the size distribution of the dispersed phase, such as the number density function or its moments. It is designed to be used exclusively with the population balance modeling functionality of the reactingEulerFoam solvers. It can be applied to a specific cellZone or the entire domain. The function type determines whether the density function and its moments are based on the number of dispersed phase elements in a size group or their total volume.

Example of function object specification:

numberDensity
{
    type           sizeDistribution;
    libs ("libmultiphaseEulerFoamFunctionObjects.so");
    ...
    populationBalance   bubbles;
    regionType          cellZone;
    name                zone0;
    functionType        number;
    coordinateType      volume;
    densityFunction     yes;
}
