TLDR
In this paper, the Richardson-Zaki equation was used to determine the settling velocity of two particle fractions in binary sedimentation, where the total particle concentration is used to correct the terminal fall velocity of the particles in each fraction.About:

Pyroclastic density currents and the sedimentation of ignimbrites
TL;DR: Bursik et al. as mentioned in this paper presented a conceptual framework for investigating how ignimbrites are deposited, integrating the results of field-based studies, laboratory experiments and numerical modelling, including work on clastic sedimentologym and industrial particle transport.

Sedimentation of noncolloidal particles at low Reynolds numbers
Robert H. Davis,Andreas Acrivos +1 more
TL;DR: Sedimentation, wherein particles fall under the action of gravity through a fluid in which they are suspended, is commonly used in the chemical and petroleum industries as a way of separating particles from fluid as discussed by the authors.
Journal ArticleDOI
Hydrodynamics of liquid fluidisation
TL;DR: Theoretical and empirical approaches to the fluid dynamic description of liquid fluidized beds are reviewed, together with the relevant experimental evidence as mentioned in this paper, with one section devoted to binary-solid systems, the particles differing in size and/or in density.
Journal ArticleDOI
Settling behaviour of concentrated dispersions and some volcanological applications
TL;DR: In this paper, the settling of poorly-sorted aqueous dispersions with low-density particles was studied to gain insight into the sedimentation behavior of volcaniclastic flows which contain pumice.

The experimental study of the differential settling of particles in suspension at high concentrations
TL;DR: In this paper, the settling behavior of unflocculated suspensions at high concentrations is discussed, and it is shown experimentally that particle segregation occurs up to a limiting concentration in excess of 30% by volume.

Experimental investigation into the settling behaviour of suspensions
R. Davies,B.H. Kaye +1 more
TL;DR: In this article, the segregation of slurries is studied for multispecies suspensions, and the values of the critical concentrations at which segregation ceases for different systems are experimentally obtained, and a mechanism derived to explain the phenomena.
