The Ups and Downs of Gas-Solid Flow - A Review

The scope of this review is confined to (i) upflow of particulate solids in a tube as occurs in vertical pneumatic conveying and riser-reactors; and (ii) downflow of particulate solids in a vertical standpipe. The aims are to present a personal view on the status of knowledge of the subjects in a structured framework and to indicate areas where further work is warranted. No attempt has been made to report all works published on the subjects and to present the conflicting conclusions reached by all the workers.
