J. Process Eng.    2019, 19 (4): 651-660.   DOI: 10.12034/j.issn.1009-606X.218338 Abstract （905）      PDF （1326KB）（580）       Knowledge map    Save Eularian?Lagrangian (EL) methods for the simulation of gas–solid flow are advantageous over Eularian–Eularian (EE) methods in terms of their more rigorous treatment of the particle motion and particle–particle interactions. But conventional EL methods are limited in the number of handled particles. Coarse-grained discrete particle method (CG-DPM) and multiphase particle-in-cell (MP-PIC) are two main methods in this category to increase the simulation scales by treating particle swarms as single computational particles. They are found to be more suitable for dense and dilute particle suspensions, respectively and hence coupled in this study to establish a more general, accurate and efficient EL method. The optimum coupling parameters are determined by comparing the flow patterns from different methods and quantitative analysis on their particle fraction distributions.

J. Process Eng.    2017, 17 (3): 427-432.   DOI: 10.12034/j.issn.1009-606X.217139 Abstract （1186）      PDF （454KB）（228）       Knowledge map    Save Chemical Engineering or Chemical Technology Process has acquired an over-expanding knowledge base involving transport and reaction as its main contents, that is popular name “3-Tranfer & 1-Reaction”, as the principle of “unit operation” design. In last twenty years we study the acid–alkali united production from metallic salts by hydrolytic action, and found that there be an essential distinction between unit operation and process. One process contains varied many unit operations. Also the essential basic theory for process is closed circular system of multi-phases dynamics. On the basic theory of process guided the ecologic recycle engineering, as the complete base of ecological circular economy at practice or theory. Related Articles | Metrics
