Solids flow pattern in gas-flowing solids-fixed bed contactors. Part I Experimental
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
An experimental investigation of the solids flow pattern in gas-flowing solids-fixed bed contactors is presented. The apparatus and procedures for determining the dynamic and static solids holdups, solids residence time ...
Solids flow pattern in gas-flowing solids-fixed bed contactors. Part II Mathematical modeling
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
In this paper a mathematical model for solids flow in gas-flowing solids-fixed bed contactors is developed. The presented four-parameter model assumes plug flow with axial dispersion in the dynamic, fast moving solids zone ...
