摘　　要：设计了一种新型低风压导线,应用开源CFD软件OpenFOAM5.0,运用大涡模拟(LES)方法对低风压导线在雷诺数为1.4×10^5工况下进行了三维仿真计算、流场分析,探究了低风压导线的减阻机理,并通过风洞试验验证了仿真设计的可信度。设计的低风压导线于2017年成功应用在国内首条低风压导线工程中。A new type of drag reduced conductor is designed,by using three⁃dimensional simulation calculation and flow field analysis of the drag reduced conductor under the reynolds number of 1.4×10^5 and using the open source CFD software OpenFOAM5.0 and LES method.The drag reduction mechanism of the conductor is explored,and the reliability of simulation design is verified by wind tunnel test.The designed conductors have been successfully applied in the first drag reduced conductor project in China in 2017.
