针对泥浆管道输送中的减阻难题，提出了一种新型减阻装置（均流器），并通过数值模拟系统分析了转速-流速比（k）、颗粒浓度（Cv）和导流叶片高度-管径比（H/D）等关键参数对其减阻性能的影响。研究表明，该均流器通过其导流叶片的旋转产生强力涡旋，将管道内原不对称流速剖面转化为对称的椭圆曲线剖面，利于管底沉积泥沙的起扬，提升管道输送减阻效果；涡旋均流器的构型参数（H/D）和运行参数（k）是影响其减阻效果的关键因素，减阻率随H/D和k的增大均呈先增后减的趋势，H/D=0.15时均流器的减阻效果最好，而运行参数k的最优值则明显受Cv的影响，泥浆浓度越大，达到最优减阻率所需的k值越大；Cv=30%时的最优k≈2.35， Cv=50%时的最优k≈5.79。这些成果可为泥浆管道节能输送提供新方法。

This paper addresses the drag reduction challenge in slurry pipeline transportation by proposing a novel drag reduction device—a rotating vortex flow conditioner. Through numerical simulation， the effects of key parameters such as the rotational speed-to-flow velocity ratio and particle concentration on its resistance reduction performance were systematically analyzed. The study demonstrates that the device can generate strong vortices via its guide vanes， transforming the originally asymmetric velocity profile into a symmetric elliptical profile. This facilitates the resuspension of sediments on the pipe bottom， thereby enhancing the resistance reduction effect of pipeline transportation. The geometric parameter (H/D) and operational parameter (k) of the device are identified as critical factors influencing its resistance reduction performance. The drag reduction rate initially increases and then decreases with both H/D and k， achieving optimal performance at H/D=0.15. The optimal k value is significantly influenced by slurry concentration (Cv)—higher Cv requires greater k to achieve optimal resistance reduction. Specifically， the optimal k is approximately 2.35 at Cv=30% and ≈5.79 at Cv=50%. These findings provide a new approach for energy-efficient slurry pipeline transportation.
