Stochastic weighted particle methods for population balance equations with coagulation, fragmentation and spatial inhomogeneity

摘要: Abstract This paper introduces stochastic weighted particle algorithms for the solution of multi-compartment population balance equations. In particular, it presents a class fragmentation weight transfer functions which are constructed such that number computational particles stays constant during events. The based on systems and each leads to algorithm numerical treatment Besides fragmentation, also consider physical processes as coagulation exchange mass with surroundings. properties compared direct simulation an existing method particles. It is found new show better performance over two methods especially significant amount large high rates.
