Modeling the axial hydrodynamics of gas-solid counter-current downers被引量:8
《Particuology》2020年第3期135-143,共9页Juanbo Liu Xinhua Liu Zhixin Zhang Hui Zhao Wei Ge 
the Strategic Priority Research Pro-gram of the Chinese Academy of Sciences(No.XDA07080400);the Informationization Program of the Chinese Academy ofSciences(No.XXH13506-301)。
Gas-solid counter-current downer reactors,in which particles move downward in an upward gas flow,can achieve high solid concentration for high heat and/or mass transfer rates.However,the particles may reverse their di...

Counter-current three-phase fluidization in a turbulent contact absorber: A CFD simulation被引量:1
《Particuology》2017年第6期51-67,共17页Syed Shah Jehan Gillani Atta Ullah Muhammad Zaman Imran Rafique Chugtai Mansoor Hameed Inayat 
A computational fluid dynamics study of three-phase counter-current fluidization occurring in a turbu- lent contact absorber was performed. A two-dimensional, transient Eulerian multi-fluid model was used, in which th...
