本文重点介绍了雷诺平均纳维尔-斯托克斯（RANS）湍流模型的当前能力及其在工业流动中的应用。这里讨论的经验是Galerkin/最小二乘有限元法和RANS湍流建模方法超过15年商业应用的结果。本文的目的是提供湍流建模的简要回顾，然后说明工业用户如何成功地利用RANS技术在生产环境中。越来越复杂的应用，包括逆压梯度，分离和复杂的3-D系统，以说明RANS和非定常RANS（URANS）建模的优势。结果还提请注意RANS技术的一些限制，工业应用的具体利益。最后，提供了在RANS建模领域继续研究的动机。
This article focuses on the current capabilities of Reynolds-Averaged Navier-Stokes (RANS) turbulence modelling and its application to industrial flows. The experiences discussed here are the culmination of over 15 years of commercial application of the Galerkin/Least-Squares Finite Element Method and RANS turbulence modelling approach. The objective of this article is to provide a brief review of turbulence modelling, then illustrate how industrial users are successfully leveraging RANS techniques in production environments. Applications of increasing complexity involving adverse pressure gradients, separation and complex 3-D systems are presented to illustrate the strengths of RANS and unsteady RANS (URANS) modelling. Results are also presented to draw attention to some of the limitations of RANS technology for industrial applications of specific interest. Finally, motivation for continuing research in the field of RANS modelling is provided.
