Turbulent Cascades II
Gathering contributions by the most prominent researchers in a highly specialised field, this proceedings volume clarifies selected aspects of the physics of turbulent cascades and their statistical universalities under complex stationary and non-homogeneous conditions. Here, these conditions are induced by the presence of a gas/liquid interface, inertial particles, strong shear, rotation, MHD and stratification. By proposing different ways to model turbulence effects under these complex conditions, the book will be of considerable interest not only to academic researchers, but also to specialists and junior researchers in the domain of propulsion and power, as well as those whose work involves various applications related to atmospheric, oceanic and planetary physics.
Complex Effects in Large Eddy Simulations
The field of Large Eddy Simulations is reaching a level of maturity that brings this approach to the mainstream of engineering computations, while it opens opportunities and challenges. The main objective of this volume is to bring together leading experts in presenting the state-of-the-art and emerging approaches for treating complex effects in LES. A common theme throughout is the role of LES in the context of multiscale modeling and simulation.
Quality and Reliability of Large-Eddy Simulations II
The second Workshop on "Quality and Reliability of Large-Eddy Simulations", QLES2009, was held at the University of Pisa from September 9 to September 11, 2009. Its predecessor, QLES2007, was organized in 2007 in Leuven (Belgium). The focus of QLES2009 was on issues related to predicting, assessing and assuring the quality of LES. The main goal of QLES2009 was to enhance the knowledge on error sources and on their interaction in LES and to devise criteria for the prediction and optimization of simulation quality, by bringing together mathematicians, physicists and engineers and providing a platform specifically addressing these aspects for LES. Contributions were made by leading experts in the field. The present book contains the written contributions to QLES2009 and is divided into three parts, which reflect the main topics addressed at the workshop: (i) SGS modeling and discretization errors; (ii) Assessment and reduction of computational errors; (iii) Mathematical analysis and foundation for SGS modeling.
Advances in Turbulence XI
This volume comprises the communications presented at the ETC 11, the EUROMECH European Turbulence conference held in 2007 in Porto. The scientific committee has chosen the contributions out of the following topics: Acoustics of turbulent flows; Atmospheric turbulence; Control of turbulent flows; Geophysical and astrophysical turbulence; Instability and transition; Intermittency and scaling; Large eddy simulation and related techniques; MHD turbulence; Reacting and compressible turbulence; Transport and mixing; Turbulence in multiphase and non-Newtonian flows; Vortex dynamics and structure formation; Wall bounded flows.
Progress in Turbulence
Besides turbulence, there is hardly any other scientific topic which has been considered a prominent scientific challenge for such a long time. The special interest in turbulence is not only based on it being a difficult scientific problem but also on its meaning in the technical world and our daily life. This carefully edited book comprises recent basic research as well as research related to the applications of turbulence. Therefore, both leading engineers and physicists working in the field of turbulence were invited to the iTi Conference on Turbulence held in Bad Zwischenahn, Gemany 21st - 24th of September 2003. Topics discussed include, for example, scaling laws and intermittency, thermal convection, boundary layers at large Reynolds numbers, isotropic turbulence, stochastic processes, passive and active scalars, coherent structures, numerical simulations, and related subjects.

Entwicklung eines Smoothed Particle Hydrodynamics (SPH) Codes zur numerischen Vorhersage des Primärzerfalls an Brennstoffeinspritzdüsen
Aufgrund der strengen Schadstoffemissionsrestriktionen zukünftiger Triebwerksgenerationen bedarf es der Entwicklung innovativer und effizienter Triebwerkskonzepte. Eine Optimierung des Zerstäubersystems ist in diesem Zusammenhang unerlässlich. Daher ist es wünschenswert, die Kraftstoffaufbereitung in der Brennkammer unter Verwendung von Airblast-Zerstäubern und insbesondere den bisher noch nicht mit ausreichender Genauigkeit modellierbaren Primärzerfall, in Zukunft numerisch vorhersagen zu können. Im vorliegenden Forschungsbericht wird systematisch untersucht, ob und inwiefern die gitterfreie Lagrange'sche Smoothed Particle Hydrodynamics Methode in diesem Kontext anwendbar ist. Hat der SPH Ansatz das Potential, den Primärzerfall in technisch relevanten Systemen exakt beschreiben zu können? Können die charakteristischen Effekte, die während des Primärzerfalls von Bedeutung sind, korrekt vorhergesagt werden? Welche Modelle sind dafür einsetzbar oder müssen in geeigneter Weise modifiziert werden? Der zentrale Teil dieses Forschungsberichts beschäftigt sich mit der Entwicklung und der umfassenden Validierung des auf der SPH Methode basierenden Strömungslösers.
Direct and Large Eddy Simulation XII
This book gathers the proceedings of the 12th instalment in the bi-annual Workshop series on Direct and Large Eddy Simulation (DLES), which began in 1994 and focuses on modern techniques used to simulate turbulent flows based on the partial or full resolution of the instantaneous turbulent flow structure. With the rapidly expanding capacities of modern computers, this approach has attracted more and more interest over the years and will undoubtedly be further enhanced and applied in the future. Hybrid modelling techniques based on a combination of LES and RANS approaches also fall into this category and are covered as well. The goal of the Workshop was to share the state of the art in DNS, LES and related techniques for the computation and modelling of turbulent and transitional flows. The respective papers highlight the latest advances in the prediction, understanding and control of turbulent flows in academic and industrial applications.
