The charge motion in a tumbling mill has been mostly described by empirical, mechanistic and computational models. The computational model presented in this work is a three phase approach for the tumbling mill that combines a particle description for the solids modelled by the Discrete Element Method, and the continuum description for the fluid by CFD approach.
CFD analysis of the small dust collector Richard Smith posted a series of articles analyzing my small dust collector on Symscape''s blog.. This analysis was primarily intended as an example demonstrating Symscape''s computational fluid dynamics dust collector was a good target because the exact geometry was readily available from my plans, and I wrote a fair bit about it on my website.
