Pump and pipeline performance when pumping slurries with different particle gradings

Godkänd; 2014; 20141210 (ninhul)
A pipeline slurry friction loss model consisting of three regimes was initially proposed by K.C. Wilson in Wilson and Sellgren (2001), then extended to a four components consisting of fluid, pseudo-homogeneous, heterogeneous and fully stratified regimes, Wilson et al. (2006). The weighting technique using up to four regime related components often works well for friction loss estimations based on simple input data and model parameters. This also holds for the ANSI/HI (2011) pump performance derating procedure for settling slurries. The comparisons and discussion focus on coarse particle slurries and some cases where the modelling estimations for pipeline and pump performance were not particularly accurate.--------------------------------------------------------------------------------
