Computational resources have developed to the level that, for the first time, it is becoming possible to apply large-eddy simulation (LES) to turbulent flow problems of realistic complexity. Many examples can be found in technology and in a variety of natural flows.

Computational resources have developed to the level that it is becoming possible to apply large-eddy simulation (LES) to turbulent flow problems of realistic complexity. This book is the first fully dedicated collection on quality and reliability of LES.

Contains the written contributions to QLES2009 and is divided into three parts, which reflect the main topics addressed at the workshop: SGS modeling and discretization errors; Assessment and reduction of computational errors; and, Mathematical analysis and foundation for SGS modeling.

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...
