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 answers to technical flow problems at reasonable computational cost. DLES-5 was attended by 111 delegates from 15 countries. Its three-day pro gramme covered ten invited lectures and 63 original contributions partially pre sented in parallel sessions. The workshop was financially supported by the fol lowing companies, institutions and organizations: ANSYS Germany GmbH, AUDI AG, BMW Group, ERCOFfAC, FORTVER (Bavarian Research Asso ciation on Combustion), JM BURGERS CENTRE for Fluid Dynamics. Their help is gratefully acknowledged. The present Proceedings contain the written versions of nine invited lectures and fifty-nine selected and reviewed contributions which are organized in four parts: 1 Issues in LES modelling and numerics 2 Laminar-turbulent transition 3 Turbulent flows involving complex physical phenomena 4 Turbulent flows in complex geometries and in technical applications.
This volume contains the Proceedings of DLES-5, the fifth international ERCOFTAC workshop on direct and large-eddy simulation which was held at the Munich university of Technology, August 27-29, 2003. It covers all aspects of DNS and LES, but also hybrid methods like RANS/LES coupling and detached-eddy simulations designed to provide answers to technical flow problems at reasonable computational cost. Being organized in four parts, the book covers issues in LES modelling and numerics in its first part, i.e. subgrid-scale modelling, wall models for LES and numerical techniques as well as error estimation.
Laminar-turbulent transition phenomena in incompressible and compressible flows form the topic of part 2. Turbulent flows involving complex physical phenomena like multiphase and non-Newtonian effects, scalar transport, combustion, compressibility and noise generation are at the heart of part 3. Turbulent flows in complex geometries bridge the gap in part 4 to practical flow configurations in aerodynamics, turbomachinery and several other applied sciences.
