Turbulence in applications

湍流在自然界和许多工程应用中都会遇到。尽管进行了广泛的努力，对湍流的全面了解似乎仍然是艰巨的。然而，近年来，主要通过从各种各样的角度采取的婴儿步骤所取得的累积进步，已显示出更多的曙光。在基础层面上，干净、各向同性和/或均匀湍流可能仍然是进一步发展的重要工具。在实验和数据缩减方面的极度勤奋，以及改进的分析（如小波分析），对于促进这条道路上的进展是必要的。预期的研究目标是进一步开发清洁湍流实验和分析，以加快进展的步伐。同时还建议继续详细研究湍流在空气动力学（风力涡轮机）、燃烧和空气分布中的作用。所提出的平行基础应用方法的一些关键优势是：1)从正在进行的工程研究努力中不断出现细节，可用于基础探索；2)将适度的基础进展立即（实时）利用到应用工程研究中。

Turbulent flow is encountered in nature and in many engineering applications. Despite extensive efforts, a complete understanding of turbulent flow appears to remain formidable. Nevertheless, the cumulative advancement achieved, mostly via baby steps approached from a wide variety of perspectives, has shed additional light in recent years. At the fundamental level, clean, isotropic and/or homogeneous turbulence will likely remain an important vehicle for further advancement. Extreme diligence both in experimentation and in data reduction, along with improved analyses (such as wavelet analysis), are necessary to enhance progress along this path. The intended research aims specifically at further exploitation of clean turbulence experimentations and analyses to hasten the pace of progress. Also proposed in parallel is the continuation of detailed studies on the roles of turbulence in aerodynamics (wind turbines), combustion, and air distribution. Some key advantages of the proposed parallel, fundamental-application approaches are: 1) continuous emergence of specifics, from the ongoing engineering research endeavour, available for the fundamental exploration, 2) immediate (realtime) exploitation of modest fundamental progresses onto the applied, engineering research.
