Budget analysis of a pseudo-single-phase transport model for slurry flows
Abstract
This study aims at understanding the influence of the various physical mechanisms involved in the transport of solid particles within slurry flows. The present model simulates such mixtures as pseudo-single-phase fluids. The approach is based on a constitutive equation, which accounts for the shear-induced particle migration. Two supplementary terms are added to this equation to account for particle buoyancy and turbulent dispersion, respectively. The present model is validated against experimental data published in the literature, and the influence of each mechanism is discussed in detail for two particle diameters
