Numerical Investigation of Slurry Pressure Drop at Different Pipe Roughness in a Straight Pipe Using CFD

Abstract Slurry flow (water–glass beads) through a horizontal pipe of diameter, 0.0549 m and length, 3.8 with two particle sizes, i.e., 125- 440-micron, has been numerically modeled investigated based on the kinetic theory slurry transportation. The effect particles interaction characteristics such as velocity profile, wall shear stress, vector regime, granular pressure temperature evaluated at different solid concentration range. It is well established that drop key parameter for design efficient pipeline system, which influenced by factors velocity, viscosity, concentration, material geometry. However, to best our knowledge, estimation roughness height range 40–60% not yet established. Therefore, in present work, numerical simulation carried out heights (Rh = 10–50 micron) Prandtl numbers, 1.34, 2.14, 3.42 5.83. parameters are calculated ( V ) 1–5 ms ?1 C w 40–60%. results procedure current validated against available experimental literature. outcomes work reveals increases increase chosen In addition, larger found have more influence pressure, distribution entire concentration. Furthermore, settling specific energy consumption also predicted discussed pipeline. findings show size number. efficiency transportation numbers evaluated. Based results, it concluded varies size, higher demonstrates consumption. fluid low number exhibits consumptions. order recommended must be transported high
