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

Pipeline systems transporting settling slurries often contain pipe sections inclined from the horizontal. The pipe inclination affects settling slurry flow and must be considered to assure safety of the system operation. Incline-induced changes in th
