Title: Evaluation of coarse coal hydrotransport data and predictive models

Abstract

Two recently published mechanistic models and three empirical correlations were used to analyze the hydrodynamic data obtained from 7.62 cm and 15.24 cm coarse particle pipeline tests. Predicted versus measured headloss gradients were plotted as a means of evaluating the ability of each method to reproduce the parameter trends exhibited by the pressure drop data. Of the five methods selected for analyzing the data, three methods were capable of predicting the headloss gradient with some certainty. A limited parameterization of these models to investigate their sensitivity of prediction is also presented. The data used in this work were obtained with coal in an experimental program conducted by the US Bureau of Mines which sought to provide coarse particle pipeline data. In these recirculating loop tests, velocity ranges of 0.3 through 4.5 m/sec were used to pump solid concentrations of up to 45% by weight. Pressure drop data were obtained for particle to pipe diameter ranges of up to 0.25 under various flow conditions. This paper describes an evaluation of the data and the models.
