Investigation of nanoparticle flow characteristics in a pulsed fluidized bed using the DQMOM method with aggregation and fragmentation nucleus
Focusing on pulsating fluidized beds, this study considers the viscous forces between particle phases during the fluidization process. A calculation model for aggregation and fragmentation nucleus is proposed. By coupling a population balance model with Euler-Euler two-fluid model and solving the population balance model using the Direct Quadrature Method of Moments (DQMOM), the flow characteristics of nanoparticle agglomerates in a pulsating fluidized bed were investigated. The results indicate that pulsating inflow significantly improves the flow distribution of nanoparticle agglomerates within the fluidized bed.
期刊介绍：
The Chemical Engineering Journal is an international research journal that invites contributions of original and novel fundamental research. It aims to provide an international platform for presenting original fundamental research, interpretative reviews, and discussions on new developments in chemical engineering. The journal welcomes papers that describe novel theory and its practical application, as well as those that demonstrate the transfer of techniques from other disciplines. It also welcomes reports on carefully conducted experimental work that is soundly interpreted. The main focus of the journal is on original and rigorous research results that have broad significance. The Catalysis section within the Chemical Engineering Journal focuses specifically on Experimental and Theoretical studies in the fields of heterogeneous catalysis, molecular catalysis, and biocatalysis. These studies have industrial impact on various sectors such as chemicals, energy, materials, foods, healthcare, and environmental protection.
