【Abstract】 Based on the plenty of experiments done by several domestic research institutes, study was made on the mechanism of solid-liquid two-phase flow and a numerical model was built for calculating the pipeline transportation parameters, such as hydraulic slope and critical transportation velocity. The model is characterized by clear input and output interface, repid and convenient operation and good precision as has been validated by a large amount of practically measured data. It has been applied in many domestic mines′ piplines to accurately calculate the transpartation parameters of the pipelines for delivering various materials, helping in saving both research cost and time.更多还原
