Abstract

Due to the huge applications of the sand-water slurries in nature and industry, the importance to study the sand-water flow increased. In this paper, the turbulent flow of sand-water slurries is experimentally studied in a closed-loop pipeline system in the laboratory. The experiments are utilized to show the effect of the variation of both the sand diameter and the sand concentration on the two-phase pressure drop and the two-phase friction factor by changing the Reynolds number and the sand volume concentration. The pressure drop is increased along with the Reynolds number.
In the experiments, three different sand diameters are used at different three concentrations with water. The diameters of the sand are 0.15, 0.3 and 0.44 mm, while the concentrations of the sand are 2.5%, 5% and 10%. The experiments show that the pressure drop and the friction factor are increased with increasing the sand diameter and the sand volume concentration. Furthermore, the pressure drop is increased for high mixture flow rates.
