摘要

利用计算流体动力学（CFD）软件，利用多相颗粒池（MP-PIC）方法，研究了两个循环流化床（CFB）反应器之间旋风分离器分离颗粒流的新概念。讨论了颗粒流划分的不同选择，提出了利用空气射流的新思路，并在部分实验室规模的循环流化床系统中进行了模拟，以研究其可行性。根据仿真结果，提出的概念可用于划分两个反应器之间的粒子流。

A novel method for controlling solids circulation between two fluidized bed reactors in a looping system

A novel concept for splitting particle flow leaving a cyclone separator between two circulating fluidized bed (CFB) reactors is investigated with computational fluid dynamics (CFD) software utilizing the multiphase particle-in-cell (MP-PIC) method. The different options for particle flow division are discussed, and the novel idea of using air jets is presented and simulated in a partial laboratory-scale CFB system to study its feasibility. Based on the simulation results, the proposed concept can be used to divide the particle stream between two reactors.

期刊介绍： The word ‘particuology’ was coined to parallel the discipline for the science and technology of particles. Particuology is an interdisciplinary journal that publishes frontier research articles and critical reviews on the discovery, formulation and engineering of particulate materials, processes and systems. It especially welcomes contributions utilising advanced theoretical, modelling and measurement methods to enable the discovery and creation of new particulate materials, and the manufacturing of functional particulate-based products, such as sensors. Papers are handled by Thematic Editors who oversee contributions from specific subject fields. These fields are classified into: Particle Synthesis and Modification; Particle Characterization and Measurement; Granular Systems and Bulk Solids Technology; Fluidization and Particle-Fluid Systems; Aerosols; and Applications of Particle Technology. Key topics concerning the creation and processing of particulates include: -Modelling and simulation of particle formation, collective behaviour of particles and systems for particle production over a broad spectrum of length scales -Mining of experimental data for particle synthesis and surface properties to facilitate the creation of new materials and processes -Particle design and preparation including controlled response and sensing functionalities in formation, delivery systems and biological systems, etc. -Experimental and computational methods for visualization and analysis of particulate system. These topics are broadly relevant to the production of materials, pharmaceuticals and food, and to the conversion of energy resources to fuels and protection of the environment.
