Flow of Highly Concentrated Fine Particulate Slurries Through Complex Geometries

Abstract

Pressure drop-velocity measurements for flow of water slurries comprised of various concentrations of narrow size fractions of fine glass beads in l.0", 1.5", 2.0" and 2.5" diameter straight pipes, and in an array of 1.0" and 2.0" pipe bends, fittings and valves were taken. Using these data friction loss coefficients, and equivalent lengths (in numbers of pipe diameters) were calculated for the various fittings. The experimental facility used in getting these data, the actual data and the preliminary analysis of the results are presented in this report.
