Pressure drop correlations for flow of slurries in pipelines were developed for each of the following four flow regimes: flow with a stationary bed, saltation flow, heterogeneous flow, and homogeneous flow. A total number of 2 848 data points, comprised of 1 912 collected from the published literature together with 936 taken using our own test pipelines and relating to ranges of the pertinent variables extensive enough to span all four flow regimes were used as the basis of these correlations. Also, these data were used in developing an associated quantitative regime delineation scheme. The correlations provide an improved predictive capability over previously available procedures and are also broader in scope. The delineation procedure developed here permits straightforward classification of the data according to the flow regime prevailing, and it is moreover inclusive of all the data and is self-consistent.read more

A three-layer model for solid-liquid flow in horizontal pipes
P. Doron,Dvora Barnea +1 more
TL;DR: In this article, a three-layer model for solid-liquid flow in horizontal pipes is proposed and the model predictions exhibit satisfactory agreement with the experimental data and existing correlations, which overcomes the limitations of the two-layer models.

Estimation of the critical velocity in pipeline flow of slurries
TL;DR: In this paper, a detailed examination of the critical velocity in pipeline flow of non-colloidal slurries was carried out, and a set of improved critical velocity correlations were established by fitting the data to various forms of the standard equation.
