Book Description
Turbulence is one of the key issues in tackling engineering flow problems. As powerful computers and accurate numerical methods are now available for solving the flow equations, and since engineering applications nearly always involve turbulence effects, the reliability of CFD analysis depends increasingly on the performance of the turbulence models. This series of symposia provides a forum for presenting and discussing new developments in the area of turbulence modelling and measurements, with particular emphasis on engineering-related problems. The papers in this set of proceedings were presented at the 5th International Symposium on Engineering Turbulence Modelling and Measurements in September 2002. They look at a variety of areas, including: Turbulence modelling; Direct and large-eddy simulations; Applications of turbulence models; Experimental studies; Transition; Turbulence control; Aerodynamic flow; Aero-acoustics; Turbomachinery flows; Heat transfer; Combustion systems; Two-phase flows. These papers are preceded by a section containing 6 invited papers covering various aspects of turbulence modelling and simulation as well as their practical application, combustion modelling and particle-image velocimetry.

Book Description
This book allows readers to tackle the challenges of turbulent flow problems with confidence. It covers the fundamentals of turbulence, various modeling approaches, and experimental studies. The fundamentals section includes isotropic turbulence and anistropic turbulence, turbulent flow dynamics, free shear layers, turbulent boundary layers and plumes. The modeling section focuses on topics such as eddy viscosity models, standard K-E Models, Direct Numerical Stimulation, Large Eddy Simulation, and their applications. The measurement of turbulent fluctuations experiments in isothermal and stratified turbulent flows are explored in the experimental methods section. Special topics include modeling of near wall turbulent flows, compressible turbulent flows, and more.

Book Description
Turbulence in Open Channel and River Flows covers turbulence and related fluid mechanics in open-channel flows, addressing both basic mechanisms and their applications. It helps readers understand the organized motion involved in turbulent flow and apply this understanding to the practice of hydraulic engineering, including mass and sediment transport. Chapters cover mathematical expansion procedures and basic fluid mechanics to help readers understand essentially physical phenomena, and present special techniques for measurement and accurate direct observation of open-channel turbulence in laboratory flumes or natural rivers. Topics related to environmental management and turbulence-related disasters are addressed. Includes detailed mathematical expansions and supporting supplements in an appendix Presents the mathematics and fluid mechanics needed to understand turbulence in open channels Includes experimental topics from the author’s research, encouraging readers to measure and accurately observe turbulence in laboratories and rivers The book is ideal for graduate students, researchers and engineers in hydraulics and hydromechanics.

Book Description
Flow visualization using photochromic dye activation (PDA) and image processing was performed in a smooth, open channel to study the turbulence beneath the shearfree and waveless, gas-liquid interface. Experiments were done over a low-Reynolds number range of 800 to 2,400 based on liquid depth and a Froude number range of 0.25 to 0.32. Turbulence quantities obtained from statistical analysis of the instantaneous streamwise velocity profiles include the mean velocity distribution, probability density function, turbulence intensity, skewness and flatness factors and Reynolds stress. On the video recordings, coherent motions of large-scale free-surface structures were qualitatively observed, namely upwellings, downdrafts, spiral eddies and streamwise vortices. Visual counting of wall events showed that the scaling of their temporal frequency with the inner variables of viscous shear stress and viscosity improved with increasing Reynolds number, yielding average ejection and bursting periods of 39 and 119 for the highest Reynolds number, respectively.
