QMOM methods for bubbly flows –potentials for simulation of pumps

The temporal and spatial development of a particle size distribution, e.g. in a bubbly flow, can be described with the so-called Population Balance Equation. It represents a continuity statement for the number density of particles in a flow. The presentation contains a comparison of two prominent approaches for solving the population balance equation, i.e. the family of Quadrature-based Moment Methods and the Method of Classes.
