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，但对湍流的完全了解似乎仍然令人敬畏。然而，近些年来取得的累积进步--主要是通过从各种不同的角度逐步实现的进展--进一步揭示了这一点。在基本层面上，清洁、各向同性和/或均匀的湍流可能仍将是进一步发展的重要工具。在实验和数据整理方面的极端努力，以及改进的分析(如小波分析)，都是促进这条道路上的进展所必需的。这项预期的研究旨在进一步开发清洁湍流实验和分析，以加快进展的步伐。同时，还建议继续对湍流在空气动力学(风力涡轮机)、燃烧和空气分配中的作用进行详细研究。拟议的并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可用于基础探索的细节，2)将适度的基础进展立即(实时)开发到应用的工程研究上。

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.
