摘　　要：在输送流体的过程中,管道介质所携带的一些微小固体颗粒,会对管道壁面造成冲蚀磨损甚至发生穿孔现象,进而造成管道泄漏。本文采用流体动力学方法,运用DPM冲蚀预测模型,研究了固体颗粒速度、颗粒直径、含砂率对T型三通管冲蚀速率的影响,分析了冲蚀磨损规律,以确定管道中冲蚀磨损最严重的部位。结果表明,流体速度越大,含砂率越大,最大冲蚀速率越大,对管道壁面造成的冲蚀磨损越严重。T型三通管发生腐蚀最严重的部位是竖直管道与水平管道的交汇处。In the process of transporting fluid,some tiny solid particles carried by the pipeline medium would cause erosion and wear on the wall of the pipeline and even perforation,resulting in pipeline leakage.In this paper,the fluid dynamics method and DPM erosion prediction model was used to study the influence of solid particles on the erosion rate of the T-tee pipe at different speeds,particle diameters and sand content rates,and analyze the erosion and wear rules,so as to obtain the most serious erosion and wear parts of the pipeline.The results showed that the greater the fluid velocity,the greater the sand content,the greater the maximum erosion rate,and the more serious the erosion and wear caused to the pipe wall.The most serious part of the corrosion of the T-shaped tee pipe was at the intersection of the vertical pipeline and the horizontal pipeline.
