How to define Boundary conditions for Quadrature Method of Moment
 

Hi guys,
I’m working on population balance model and have some issues with the definition of QMOM boundary conditions.

I used to work with descretization method and there BC was quite simple to define. It was either a log normal or a manual distribution but here with method of moment it is confusing. I can't understand how to set up a boundary value for each moment.

I'm using fluent 18.2 with the mixture multiphase method. The only phenomena occur here is growth rate (2.8e-8 m/s) and the particle min and max size are 1e-7m 1e-5m respectively.



Any comment would be highly appreciated.
