“…The vital information against the input should be limited for the design of slurry transport. The " Area Index " data box on the table represents the shape factor 5) of irregular-shaped solids such as: sand, 1.5; coal, 1.7 6) . The data boxes of " Index of Power Function " and " Coefficient of Power Function " were prepared for representing the λ-Re relationship in the form of power function which indicates the characteristics of water flow in pipelines.…”

The transport conditions of solids in slurry pipelines cause the flow behavior of solid-liquid mixture to vary strongly and affect the hydraulic gradients in the systems. Since any transport design or correlation for slurry transport should be confirmed by a wide range of data, experiments in various flow regimes have been carried out over the years by different researchers.This study was, therefore, aimed at developing a slurry transport database for accumulation, input, editing, sorting, storing of the data available in literature and displaying the results in graphical form for comparison. A basic processing procedure was adopted for the design of the program. Then a flowchart of the program was developed to process the data. The flowchart consisted of three subflowcharts: input-for the input and addition of data； editing-for modifying and standardizing all the data into the Excel CSV form； and graph displays of the data-for comparison of the researchers' data on log-log graphs. Star graphs were used to give a clear description of the transport conditions for each researcher. The database was applied for the verification of proposed correlations for predicting the hydraulic gradients of slurry flow in pipes.

For the safety of the transportation system of a slurry pipeline, it is very important to catch the behavior of the flow in the pipe. Hydraulic pressure, mean velocity, and delivered concentration are, in general, measured for monitoring the settling slurry flow. However the flow patterns in the pipe at any moment can not directly be shown with these data. A video camera system for the monitoring is probably not useful for the opaque pipelines, or even the pipelines with transparency parts, because the flow becomes muddy under practical transport conditions.In this study, we provided a method for predicting the solid particle motion and the distributions of in-situ concentrations of the solid based on collected measurements. The method was capable of displaying the flow modes on a monitoring screen by using the random model associated with the concentration distribution of solid particles. Comparison of predicted and experimental images indicated that the proposed system was effective for monitoring solid-water mixture flows.
