要約

This paper shows a numerical simulation of horizontal slurry flow (water-glass bead) of coarse particles suspensions in a Newtonian carrier fluid. Glass bead slurry in water having 440 μm mean diameter particles is analyzed through 54.9 mm diameter pipe at volumetric concentrations up to 50% flowing with varying flow velocities up to 5 m/s. A computational fluid dynamics Eulerian model with RNG k–ε turbulence closure is adopted to analyze monodispersed glass bead particles of density 2470 kg/m3. The modeling results are compared with experimental data obtained for concentration profiles at a central vertical plane using a γ-ray densitometer and pressure drop along the pipeline using differential pressure transducers. Qualitative aspects of this analysis have also been presented in this paper.
