书籍简介

专家回顾了湍流研究的新进展，重点关注了最近发现的有组织结构。

本书回顾了塑造地球表面的湍流研究的新进展，特别关注了近年来在湍流中发现的有组织结构。这些相干流结构可以包括单个颗粒尺度的涡流或涡旋，以及与河流或河口的流动深度成比例的结构，以及形态或地貌尺度的大规模流动结构。这些流动结构引起了科学界的广泛兴趣，因为它们在流体动力学中发挥着重要作用，并影响着各种流体流动环境中沉积物和污染物的输送、侵蚀和沉积。

随着计算流体动力学在建立我们对广泛尺度上的相干流结构的理解方面发挥越来越重要的作用，对这些结构的科学认识在过去 20 年里得到了极大的提高。

章节包括一系列重要的受邀论文和在 2011 年 8 月 3 日至 5 日于不列颠哥伦比亚省本拿比市西蒙弗雷泽大学举行的第二届相干流结构会议上发表的一系列新颖、具创新性的论文。

章节重点关注六个主要主题：

地球物理流中相干流结构 (CFS) 的动力学

湍流、植被和生态栖息地的相互作用

大气流的相干结构

相干流结构的数值建模

明渠流中的湍流

相干流结构、泥沙输送和形态反馈。

An expert review of recent progress in the study of turbulent flows with a focus on recently identified organized structures. 

This book reviews the recent progress in the study of the turbulent flows that sculpt the Earth’s surface, focusing in particular on the organized structures that have been identified in recent years within turbulent flows. These coherent flow structures can include eddies or vortices at the scale of individual grains, through structures that scale with the flow depth in rivers or estuaries, to the large-scale structure of flows at the morphological or landform scale. These flow structures are of wide interest to the scientific community because they play an important role in fluid dynamics and influence the transport, erosion and deposition of sediment and pollutants in a wide variety of fluid flow environments. 

Scientific knowledge of these structures has improved greatly over the past 20 years as computational fluid dynamics has come to play an increasing important part in building our understanding of coherent flow structures across a broad range of scales.

Chapters comprise a series of major, invited papers and a selection of the most novel, innovative papers presented at the second Coherent Flow Structures Conference held August 3-5, 2011 at Simon Fraser University in Burnaby, British Columbia. 

Chapters focus on six major themes:

Dynamics of coherent flow structures (CFS) in geophysical flows

Interaction of turbulent flows, vegetation and ecological habitats

Coherent structure of atmospheric flows

Numerical modeling of coherent flow structures

Turbulence in open channel flows

Coherent flow structures, sediment transport and morphological feedbacks.
