Quality and Reliability of Large-Eddy Simulations II [Hardcover]

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). Thefocus of QLES2009 was on issues related to predicting, assessing and assuring thequality of LES.The main goal of QLES2009 was to enhance the knowledge on error sources andon their interaction in LES and to devise criteria for the prediction and optimizationof simulation quality, by bringing together mathematicians, physicists and engineersand 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 dividedinto three parts, which reflect the main topics addressed at the workshop: (i) SGSmodeling and discretization errors; (ii) Assessment and reduction of computationalerrors; (iii) Mathematical analysis and foundation for SGS modeling.Part I SGS modeling and discretization errors: Error-landscape assessment of large-eddy simulations: a review, by Johan Meyers; Numerical and physical instabilities in massively parallel LES of reacting Flows, by Thierry Poinsot; Quality Issues of Combustion LES, by A M Kempf, M Pettit; Energy cascade and spatial fluxes of filtered wall-turbulent flows, by A.
