In many industrial applications, settling slurries composed of coarse solid particles (typically sand or gravel) and Newtonian-carrying fluid (typically water) are transported in pipelines. Turbulent flow of such slurries consumes significantly more

Sand-water slurry was investigated on an experimental pipe loop of inner diameter D = 100 mm with the horizontal, inclined, and vertical smooth pipe sections. A narrow particle size distribution silica sand of mean diameter 0.87 mm was used. The expe

For the safe and economical design and operation of freight pipelines it is necessary to know slurry flow behaviour in inclined pipe sections, which often form significant part of pipelines transporting solids. Fine-grained settling slurry was invest

Pipe flows of bimodal aqueous slurries of two fractions of sand (coarse sand of particle mass-median size of 1.56 mm and fine-to-medium sand of mass-median size of 0.22 mm) are tested in a laboratory loop (pipe internal diameter of 100 mm) to study t

The radial discharge jet from the standard Rushton turbine was investigated by the Laser Doppler Anemometry (LDA) method. Several distances from the impeller blades (in radial direction) were chosen for the measurement of axial profiles: all three ve

Volume 5: Multiphase Flow.
Partially stratified flows like flows of sand-water slurries exhibit non-uniform distribution of solids (expressed as a vertical profile of local volumetric concentration) in a pipe cross section. The solids distribution in such flows is sensitive to

Inclined slurry flows occur often in industrial applications such as mining and dredging. Pipelines transporting slurries contain inclined sections of various lengths and slopes. If the transported slurry is settling slurry then pipe inclination cons
