Stochastic weighted particle methods for population balance equations with coagulation, fragmentation and spatial inhomogeneity
Problems concerning multi-compartment population balance equations are studied. A class of fragmentation weight transfer functions is presented. Three stochastic weighted algorithms are compared against the direct simulation algorithm. The numerical errors of the stochastic solutions are assessed as a function of fragmentation rate. The algorithms are applied to a multi-dimensional granulation model.
