摘　　要：本文利用计算流体动力学软件Fluent,对助推短节在管道内的三维流场进行了详细的数值模拟仿真。探讨了助推短节在不同工况下,其内部流场的流动状态变化规律。通过仿真分析,得出了助推短节在四个不同短节间距下(20mm、25mm、32mm、40mm)流速分布及压力变化等。计算得出助推短节前后压差与反作用力的变化的曲线图。研究结果对助推短节的设计优化、性能评估及工程应用具有重要的指导意义。This paper provides a detailed numerical simulation of the 3 D flow field in the pipeline by using the computational fluid dynamics software Fluent.This paper discusses the change pattern of the internal flow field under different working conditions.Through simulation analysis,the flow velocity distribution and pressure change under four different short segment intervals(20mm,25mm,32mm and 40mm)are obtained.The graph of the change of pressure difference and reaction force before and after the short section is calculated.The results have important implications for the design optimization,performance evaluation and engineering application of booster knots.
