Solid–Liquid Flow at Higher Concentration Through Bend

Abstract

Slurry flow through a pipe bend is of most important concern as it contributes not only to high pressure drop and prone to extra erosion in the pipeline. Pipe bends also provide flexibility in a route of slurry pipelines. Pipe bends acquire relatively higher pressure drop. In this paper, experimental data generated for pressure drop 25 µm on fly ash slurry through 50 mm diameter of pipeline with velocity in the range 1–4 m/s at average efflux concentration of 32.52–46.61% (by volume) using the experimental setup (pilot test loop) facility and to carry out numerical simulations (CFD) using Ansys Fluent software intended for better visualization of complex flow pattern. Furthermore, simulated results have also been presented for qualitative analysis of fly ash slurry at the bend.
