摘　　要：三通是高压管汇中的常用部件,长期处于高压环境且受到固体颗粒的冲蚀,直接影响系统的安全运行及管道的使用寿命。针对高压三通管汇冲蚀问题,在自建的可对试样施加动载的液固两相冲蚀试验台上进行试验,提出一种动载作用下的冲蚀模型,并嵌入数值模拟软件中对不同空间角度的三通结构在不同内压、流速及颗粒质量流量下的冲蚀规律进行分析。结果表明:不同三通结构的最大冲蚀率均随内压的增加而增加,随流速的增加呈指数增加,随颗粒质量流量的增加线性增加,且三通空间角度越大,增长速率越快。三通结构空间夹角增大时,最大冲蚀率增加,该规律不随内压、流速及颗粒质量流量的变化而变化。其结果可为高压三通管汇安全运营提供一定的参考依据。T-pipe is a common component in high-pressure manifolds,which are in high-pressure environments while subjected to solid particles erosion for a long term,which subsequently affects the safe operation of the relevant system and the service life of pipelines.Herein,the erosion behavior of the highpressure tee manifold was assessed via a home-made liquid-solid two-phase erosion test bench,which can apply dynamic load on the tested t-pipe subjected to erosion.A model was proposed for description of erosion under dynamic load,and then coupled with a numerical simulation software,to analyze the erosion performance of tee structures at various spatial angles under different internal pressures,velocities,and particle mass flows.Results show that the maximum erosion rate of different tee structures increases with the increase of internal pressure,exponentially with the increase of flow rate,linearly with the increase of particle mass flow rate,and the greater the tee space angle,the faster the growth rate.When the space angle of the tee structure increases,the maximum erosion rate increases,while the erosion performance does not change with the change of internal pressure,velocity,and particle mass flow rate.The results can provide reference for the safe operation of the high-pressure tee manifold.
