    采用SST和标准k-e湍流模型，数值计算了一个带有8个弯曲通道的单径向旋流器。结果表明， SST模型的计算结果更接近于水力实验结果。本文研究径向旋流器的旋流数对回流区的影响，为径向旋流器的设计提供参考。

    The SST and k-e turbulence model are used to investigate the aerodynamics of the radial swirler with 8 curved vanes. The results showed that the CFD model with SST turbulence model is in agreement with the flow visualization. The effects of swirl number on recirculation are also investigated to provide a reference for designation.
