Liutex and Its Applications in Turbulence Research reviews the history of vortex definition, provides an accurate mathematical definition of vortices, and explains their applications in flow transition, turbulent flow, flow control, and turbulent flow experiments. The book explains the term "Rortex" as a mathematically defined rigid rotation of fluids or vortex, which could help solve many longstanding problems in turbulence research. The accurate mathematical definition of the vortex is important in a range of industrial contexts, including aerospace, turbine machinery, combustion, and electronic cooling systems, so there are many areas of research that can benefit from the innovations described here. This book provides a thorough survey of the latest research in generalized and flow-thermal, unified, law-of-the-wall for wall-bounded turbulence. Important theory and methodologies used for developing these laws are described in detail, including: the classification of the conventional turbulent boundary layer concept based on proper velocity scaling; the methodology for identification of the scales of velocity, temperature, and length needed to establish the law; and the discovery, proof, and strict validations of the laws, with both Reynolds and Prandtl number independency properties using DNS data. The establishment of these statistical laws is important to modern fluid mechanics and heat transfer research, and greatly expands our understanding of wall-bounded turbulence.

A review is made of the present state of our knowledge of the vortex wakes of conventional aircraft. Included are discussions of wake rollup, geometry, instability, and turbulent aging. In the light of these discussions, a brief review is made of the persistence of vortices in the atmosphere, and design techniques which might be used to minimize wake hazard are considered.

With the increasing slenderness and lightness of civil engineering structures such as tower blocks and bridges, wind effects on them have been attracting considerable interest from researchers and design engineers. Since most structures in civil engineering present bluff forms to the wind, the main emphasis of this collection of papers is on bluff body aerodynamics. The flow effects in this case, in addition to turbulence effects in the atmospheric boundary layer illustrate the unique and complex nature of the problems that can be encountered in this field, as opposed to the classical studies in the aeronautical field that influenced the initial development stages of industrial aerodynamics. Selected papers from the colloquium are presented in this volume. The papers offer a comprehensive presentation of the results of the studies made of wind effects on engineering structures. The latest trends in the field are outlined and the results obtained in the solution of topical problems are described.

Vortex dynamics is a natural paradigm for the field of chaotic motion and modern dynamical system theory. However, this volume focuses on those aspects of fluid motion that are primarily controlled by the vorticity and are such that the effects of the other fluid properties are secondary.
