C.T. Jayasundara, Auteur ; R.Y. Yang, Auteur ; A. B. Yu, Auteur |Particle flow in a stirred mill was modeled using discrete element method, focusing on the effect of mill properties and stirrer configurations, such as particle-wall friction, the size of disc holes, distance between stirrers, and stirrer shape[...]

G. R. Chandratilleke, Auteur ; Y. C. Zhou, Auteur ; A. B. Yu, Auteur |The discrete element method (DEM) offers the possibility of understanding mixing processes at a microscopic, particle level. In connection with previous studies, DEM is used in this work to investigate the mixing of monosized spherical particles[...]

X. F. Dong, Éditeur scientifique ; A. B. Yu, Éditeur scientifique ; J. M. Burgess, Éditeur scientifique |A mathematical model for the four-phase (gas, powder, liquid, and solids) flow in a two-dimensional ironmaking blast furnace is presented by extending the existing two-fluid flow models. The model describes the motion of gas, solid, and powder p[...]
