An extended quadrature-based moment method with log-normal kernel density functions

摘要: Abstract An extended quadrature method of moments (EQMOM) with log-normal kernel density functions is developed in this work, and applied to the solution a population balance equation (PBE) for aggregation breakup, coalescence, condensation problems. The cases one two are studied analytically, existence an analytical shown. A numerical procedure based on work Yuan et al. (2012) adopted address larger number functions. Results reconstructed function (NDF), time evolution zero-order moment mean particle size compared those obtained from rigorous PBE reported by Vanni (2000) breakup. problem concerning coalescence regarding condensation, both solution, also examined. results proposed approach provided EQMOM gamma densities. Satisfactory were distribution. Excellent agreement was observed between approximated total size.
