The workshop 'Direct and Large-Eddy Simulation-4' was held at the Uni- versity ofTwente, July 18-20, 2001. DLES4is part of a series ofERCOFfAC workshops that originated at the University of Surrey in 1994. Over the years the DLES-series has grown into a major international venue focused on the development and application of direct and large-eddy simulation. Fundamental turbulence - and modeling issues but also elements from modem numerical analysis are at the heart of this field of interest, a fact which is clearly reflected by the contents of these proceedings. Modeling and simulation of...

This volume contains selected presentations of the "EUROMECH Colloquium 412 on LES of complex transitional and turbulent flows" held at the Munich University of Technology from 4 to 6 October 2000.

The articles focus on new developments in the field of large-eddy simulation of complex flows and are related to the topics: modelling and analysis of subgrid scales, numerical issues in LES cartesian grids for complex geometries, curvilinear and non-structured grids for complex geometries. DES and RANS-LES coupling, aircraft wake vortices, combustion and magnetohydrodynamics.

The fifth ERCOFfAC workshop 'Direct and Large-Eddy Simulation-5' (DLES-5) was held at the Munich University of Technology, August 27-29, 2003. It is part of a series of workshops that originated at the University of Surrey in 1994 with the intention to provide a forum for presentation and dis cussion of recent developments in the field of direct and large-eddy simula tion. Over the years the DLES-series has grown into a major international venue focussed on all aspects of DNS and LES, but also on hybrid methods like RANSILES coupling and detached-eddy simulation designed to provide reliable...

The scientific work described in this book is the result of an international coopera- tion of over 60 researchers from many different European countries over more than 10 years. Considerable advances have been made in the development, appli- cation and improvement of methods and models for the calculation of emissions. Work on the quantification of uncertainties of emission data could be enhanced and carried out and uncertainty assessments conducted. The developed methods present the current state of the art in this field. Collaboration of teams has taken place under the EUROTRAC, the EUREKA...

The end result of policy-related experimental and theoretical scientific work on the abatement of atmospheric emissions is a hierarchy of computer models that can be used to analyse and predict the behaviour of pollutants on urban, local regional and global scales. Such models are required to simulate an extremely complex natural situation in which a non-linear chemistry must be included together with the vagaries of the meteorology and the terrain. This book describes recent advances in the development and application of models on all scales, and in the techniques for the estimation and...

The sixth ERCOFTAC Workshop on Direct and Large-Eddy Simulation (DLES-6) was held at the University of Poitiers from September 12-14, 2005. Following the tradition of previous workshops in the DLES-series, this edition has reflected the state-of-the-art of numerical simulation of transitional and turbulent flows and provided an active forum for discussion of recent developments in simulation techniques and understanding of flow physics.

Transport is very important for the economy and our welfare. However, transport also causes a lot of problems, including air pollution. Such problems should be taken into account, when making decisions. A prerequisite for doing so is, that the impacts are known, quantitatively measured and allocated to the different activities in transport. Furthermore, they should be transformed into monetary units to be used as a basis for cost-benefit analyses or as an aid for setting taxes and charges, that reflect the external costs. This book describes a methodology for calculating impacts of transport...
