Study on Transient Flow Simulation in Solid-liquid Slurry Pipeline

WU Du-xi(Changsha Research Institute of Mining and Metallurgy Co Ltd,Changsha 410012,Hunan,China)  
In view of transient flow occurred in solid-liquid two-phase transportation pipeline,the continuity equation,equation of motion,as well as corresponding characteristic equations were deduced for the transient flow by using fluid mechanics and theory of two-phase flow.Then,a mathematical model was established for the transient flow in two-phase flow pipeline.The software of Hydraulic Transport was developed for calculation of transient flow by introducing multi-threaded technology,resulting in the calculation time greatly reduced.By applying this software into the slurry pipeline of iron concentrate,the calculation result obtained is basically in conformity with practical measurement,proving the efficiency of this mathematical model.
