24 Class
25  Foam::functionObjects::sizeDistribution
26 
27 Description
28  This function object calculates and outputs volume-averaged information
29  about the size distribution of the dispersed phase, such as the number
30  density function or its moments. It is designed to be used exclusively with
31  the population balance modeling functionality of the multiphaseEulerFoam
32  solver. It can be applied to a specific cellZone or the entire domain. The
33  function type determines whether the density function and its moments are
34  based on the number of dispersed phase elements in a size group or their
35  total volume.
36 
37  Example of function object specification:
38  \verbatim
39  numberDensity
40  {
41  type sizeDistribution;
42  libs ("libmultiphaseEulerFoamFunctionObjects.so");
43  ...
44  populationBalance bubbles;
45  regionType cellZone;
46  name zone0;
47  functionType number;
48  coordinateType volume;
49  densityFunction yes;
50  }
51  \endverbatim
52 
53 Usage
