TLDR
The sliding bed theory of deposition has been compared with a range of experimental results most of them not previously published as discussed by the authors, and the results for higher viscosity fluids do not show such good agreement.About:

Hyperconcentrated Flow and Sediment Transport at Steep Slopes
TL;DR: In this article, the effect of an increasing fluid density and viscosity on the flow behavior and the bed-load transport capacity of a fine-material slurry of a debris flow was examined.

Slurry flow in horizontal pipes—experimental and modeling
P. Doron,D. Granica,Dvora Barnea +2 more
TL;DR: In this paper, a physical model for the prediction of the pressure drop and flow patterns is presented for the hydraulic transport of coarse particles in horizontal tubes, which is compared with new experimental data and shows good agreement.
Journal ArticleDOI
Estimation of the critical velocity in pipeline flow of slurries
TL;DR: In this paper, a detailed examination of the critical velocity in pipeline flow of non-colloidal slurries was carried out, and a set of improved critical velocity correlations were established by fitting the data to various forms of the standard equation.
DissertationDOI
Bedload transport capacity of slurry flows at steep slopes
TL;DR: In this paper, the effect of an increasing fluid density and viscosity on the bed load transport capacity of the flow was examined, and two different calculation procedures were proposed to determine the unknown parameters of flow of the grain-fluid mixture.
Journal ArticleDOI
Calculation of critical velocities to maintain solids in suspension in horizontal pipes
TL;DR: In this paper, a simple theoretical justification of the empirical results for the flow velocities required just to suspend solid particles in horizontal pipes is deduced from turbulence theory, which gives a better fit to the empirical data than does the Durand relation.

Turbulent disruption of flocs in small particle size suspensions
TL;DR: In this paper, it was shown that in the presence of turbulent fluctuations the main effect of a velocity gradient on floc properties is a rearrangement of particles within the floc producing a more dense floc structure.

Transport characteristics of suspensions: Part VI. Minimum transport velocity for large particle size suspensions in round horizontal pipes
TL;DR: In this article, the minimum transport velocity required to prevent the accumulation of a layer of stationary or sliding particles on the bottom of a horizontal conduit was determined in a 1-in. pipe for an aqueous suspension of glass beads using glass beads having mean diameters of 78 and 310 μ.

Transport characteristics of suspensions: ii. minimum transport velocity for flocculated suspensions in horizontal pipes
TL;DR: In this article, the minimum transport velocity was determined for flocculated thorium oxide and kaolin suspensions flowing in glass pipes, and two flow regimes were observed depending on the concentration of the suspension.
Journal ArticleDOI
Slip Point of Beds in Solid-Liquid Pipeline Flow
TL;DR: In this paper, it is shown that near the slip point, the granular pressure at the periphery of the bed follows a hydrostatic distribution, and that the pressure gradient at this point is directly proportional to the underwater weight per unit volume of bed, and increases with the angle subtended by the deposit.
