Available in PDF, EPUB and Kindle. Book excerpt: This book provides students and researchers in fluid engineering with an up-to-date overview of turbulent flow research in the areas of simulation and modeling. A key element of the book is the systematic, rational development of turbulence closure models and related aspects of modern turbulent flow theory and prediction. Starting with a review of the spectral dynamics of homogenous and inhomogeneous turbulent flows, succeeding chapters deal with numerical simulation techniques, renormalization group methods and turbulent closure modeling. Each chapter is authored by recognized leaders in their respective fields, and each provides a thorough and cohesive treatment of the subject.

Download or read book Turbulent Flows written by G. Biswas and published by CRC Press. This book was released on 2002 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The present work investigates turbulent velocity and temperature fields subject to strong wall injection in a channel using a Direct Numerical Simulation technique. A simplified model problem of the internal flows inside the hybrid rocket motors where a regression process at the wall is idealized by the wall blowing has been considered to gain a better understanding of how the turbulent structures are modified. Since the near-wall state of turbulence is likely to be modified due to the effect of wall blowing and the mean flow dynamics differ significantly from those in typical non-transpired channel flows, caution needs to be made when the RANS type calculations are to be performed. As the strength of wall blowing increases, the flow experiences stronger streamwise acceleration or inhomogeneity and both the wall shear and friction temperature decrease significantly, but many of the higher order statistics such as turbulence intensities, turbulent heat flux, r.m.s. temperature fluctuations and Reynolds shear stress increase rapidly as the flow moves downstream, and this is thought to result from the shear instability induced by wall injection. Also, turbulent viscosity and turbulent diffusivity grow rapidly. Thus, the effect of wall-blowing modifies the state of turbulence significantly and more sophisticated turbulence modeling is required to predict this type of flow accurately.
Download or read book DNS of Wall Bounded Turbulent Flows written by Tapan K. Sengupta and published by Springer. This book was released on 2018-06-07 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights by careful documentation of developments what led to tracking the growth of deterministic disturbances inside the shear layer from receptivity to fully developed turbulent flow stages. Associated theoretical and numerical developments are addressed from basic level so that an uninitiated reader can also follow the materials which lead to the solution of a long-standing problem. Solving Navier-Stokes equation by direct numerical simulation (DNS) from the first principle has been considered as one of the most challenging problems of understanding what causes transition to turbulence. Therefore, this book is a very useful addition to advanced CFD and advanced fluid mechanics courses.
