摘要： 基于计算流体力学(CFD)理论，研究了不同曲率半径的螺旋导流片的托卡马克真空室内线圈水冷管道接头。利用湍流数值模拟方法，分析了线圈管道接头导流片曲率半径比、冷却水入口流速对线圈管道内流体平均雷诺数分布的影响。结果表明，不同导流片曲率半径比的线圈管道内的流体雷诺数分布曲线相似，平均雷诺数随入口流速的增加而增大，管道接头出口雷诺数随导流片曲率半径比的增大而减小，导流片曲率半径比小的管接头更适用于线圈水冷曲线管的二次流强化。此外，还为导流片曲率半径比为0.2的管接头拟合了管接头出口雷诺数与入口流速的关系式，为进一步研究类似于托卡马克真空室内线圈管道的曲线管接头的二次流强化提供理论基础。

Abstract: The tokamak in-vessel coil water-cooling pipe joints of different deflector curvature radius ratios are studied based on the computational fluid dynamics (CFD). The impact on the average Reynolds number distribution from the coils water-cooling pipe of different ratio of the coil pipe joint deflector curvature radius and related inlet velocity has been analyzed, using turbulence numerical simulation method. The results indicate that the average Reynolds number distribution curves of different deflector curvature radius ratio are similar, and the numbers increase with the increase of inlet velocity, while the outlet Reynolds numbers of the pipe joint decrease with the increase of the deflector curvature radius ratio. The deflector of the small curvature radius ratio is more suitable for the secondary flow enhancement of the coil water-cooling curved pipe. In addition, the relationship between the outlet Reynolds numbers of the coil joint and its inlet velocity is fitted for the pipe joint with deflector curvature radius ratio of 0.2, which provides a theoretical basis for further study of the secondary flow enhancement of the similar curved pipe joint with tokamak in-vessel coil pipe.

Key words: Curved pipe of in-vessel coils, Pipe joint, Deflector, Curvature radius ratio
