"This book is intended for self-study or as a companion of lectures delivered to post-graduate students on the subject of the computational prediction of complex turbulent flows. There are several books in the extensive literature on turbulence that deal, in statistical terms, with the phenomenon itself, as well its many manifestations in the context of fluid dynamics. Statistical Turbulence Modelling for Fluid Dynamics — Demystified differs from these and focuses on the physical interpretation of a broad range of mathematical models used to represent the time-averaged effects of turbulence in computational prediction schemes for fluid flow and related transport processes in engineering and the natural environment. It dispenses with complex mathematical manipulations and instead gives physical and phenomenological explanations. This approach allows students to gain a 'feel' for the physical fabric represented by the mathematical structure that describes the effects of turbulence and the models embedded in most of the software currently used in practical fluid-flow predictions, thus counteracting the ill-informed black-box approach to turbulence modelling. This is done by taking readers through the physical arguments underpinning exact concepts, the rationale of approximations of processes that cannot be retained in their exact form, and essential calibration steps to which the resulting models are subjected by reference to theoretically established behaviour of, and experimental data for, key canonical flows."--

This volume contains 37 invited contributions, collected to celebrate one hundred volumes of the NNFM Series. After a general introduction overviews are given in five parts of the developments in numerical fluid mechanics and related fields. In the first part information about the series is given, its origins are discussed, as well as its environment and the German and European high-performance computer scene. In Part II the co-editors of the series give short surveys over developments in their countries. Current applications, mainly in the aerospace sector, but also in the automotive sector, are discussed in Part III. Applications to flow problems in engineering and physics, ranging from hydraulic machinery to astrophysics, are the topics of Part IV. Algorithms, computer science, commercial CFD, public partnerships in high-performance computing, and hardware development up to petaflops computers are treated in Part V. All volumes, which were published in the series finally are listed in Part VI.

This volume contains the contributions to the scientific anniversary colloquium in honor of the 100th birthday of Hermann Schlichting, Braunschweig, September 2007. His outstanding achievements in boundary layer theory and aircraft aerodynamics are reviewed by invited scholars. Contributions of current leading research by the institutes formerly lead by Hermann Schlichting, the Institute of Fluid Mechanics of the Technische Universität Braunschweig and the Institute of Aerodynamics and Flow Technology of German Aerospace Center, in the fields of numerical flow simulation, experimental techniques, wing aerodynamics and turbomachinery highlight the lasting impact of his work until today.

This volume contains seven keynote lectures of the TI 2006 conference that was held in Porquerolles, May 29-June 2, 2006. These lectures address the latest developments in direct numerical simulations, large eddy simulations, compressible turbulence, coherent structures, bubbly channel flows, combustion. The keynote lectures are extended manuscripts that were not published in the special issues of the journals "Computers and Fluids" and "Flow, Turbulence and Combustion". The present monograph is a snapshot of the state-of-the-art in the field of turbulence with a view on theory, experiments and numerical simulations.
