On the systematics of rheological measurements of gas fluidized grains [PDF]

open access: yesEPJ Web of Conferences
There have been many attempts to characterize the flow behavior of fluidized and non-fluidized granular particles [1–4]. The well-known Geldart classification [5] divides granular particles by their fluidization characteristics and the rheology of air ...
