(Two-phase liquid–solid flow (hydraulic transport
Hydraulic transport is the conveyance of particulate matter in liquids. Although
most of the earlier applications of the technique used water as the carrier
medium (and hence the term hydraulic), there are now many industrial plants,
particularly in the minerals, mining and power generation industries, where
particles are transported in a variety of liquids which may exhibit either
Newtonian or non-Newtonian flow behaviour. Transport may be in vertical or
horizontal or inclined pipes, but in the case of long pipelines, it may follow the
undulations of the land over which the pipeline is installed. The diameter and
length of the pipeline and its inclination, the properties of the solids (size,
shape and density) and of the liquid (density, viscosity, Newtonian or non-
Newtonian), and the flow rates all influence the nature of the flow and the
pressure gradient. Design methods are, in general, not very reliable, especially
for the transportation of coarse particles; Therefore, the estimated values of
