Keywords:
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.

"Filled with state-of-the-art information on turbulence model development. . .This book presents shining examples of the advances over the past decade or two."--Bulletin of the American Meteorological Society "Essential to turbulence workers and students. . . .Belongs in all technical libraries. . . .Ideal for a second course in turbulence. The book's price, under $40, should be attractive to all, especially students. It gives the most value per dollar (~11 cents per page) yet seen by this reviewer."--Applied Mechanics Reviews "Filled with state-of-the-art information on turbulence model development. . .This book presents shining examples of the advances over the past decade or two."--Bulletin of the American Meteorological Society "Essential to turbulence workers and students. . . .Belongs in all technical libraries. . . .Ideal for a second course in turbulence.
