WebbThis process is referred to as hindered settling. Of the sediment particle settling velocities presented above, only the Soulsby (1997) formula considers this process. When using … WebbIn the current literature, information can mainly be found about free and hindered settling of isometric particles in Newtonian and non-Newtonian fluids. These conclusions cannot be used to describe the sedimentation of non-isometric particle in non-Newtonian fluids. For this reason, we have carried out systematic experiments and calculated the …

WebbThis model naturally extends the Richardson-Zaki formalism used to describe hindered settling of hard, repulsive spheres. Experimental measurements of the collective … WebbA revision of the popular equation of Richardson and Zaki (1954a, Transactions of the Institute of Chemical Engineering, 32, 35–53) for the hindered settling of suspensions of non- cohesive particles in fluids is proposed, based on 548 data sets from a broad range of scientific disciplines.
