Turbulence in applications

湍流在自然界和许多工程应用中都会遇到。 尽管作出了广泛的努力，但对湍流的全面了解似乎仍然是艰巨的。 尽管如此，近年来所取得的累积进步（主要是通过从各种角度迈出的小步）为我们提供了更多的启示。 在基本水平上，清洁的、各向同性的和/或均匀的湍流可能仍然是进一步发展的重要工具。 在实验和数据处理方面的极端努力，沿着改进的分析（如小波分析），是促进沿着这条道路取得进展所必需的。 同时还提出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。 所提出的并行的基础应用方法的一些关键优点是：1）从正在进行的工程研究努力中不断出现可用于基础探索的细节，2）立即（实时）利用应用工程研究的适度基础进展。

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.
