Ebook: Direct and Large-Eddy Simulation IV

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 complex flow phenomena forms a central ele­ ment in a large volume of scientific - and applied research. The problem of simulating turbulent flows and capturing their main dynamical features remains a highly motivating challenge. This three-day workshop focused on recent de­ velopments in numerical and physical modeling of complex flow phenomena concentrating on modem strategies in the field of direct and large-eddy simula­ tion. A major aim was to promote the exchange of ideas and problems from both industrial and academic background paying attention to physical, mathematical and engineering aspects.

This volume contains the proceedings of DLES4, the fourth international ERCOFTAC workshop on direct and large-eddy simulation which was held at the University of Twente, July 18-20, 2001. It contains an exposition and discussion of state-of-the-art modeling and simulation approaches for complex flows. Fundamental turbulence - and modeling issues but also elements from modern numerical analysis are at the heart of this field of interest. Present-day DNS and LES tend to be extended toward flows of realistic complexity, at practically relevant flow conditions and with the inclusion of additional complex physical phenomena such as arise e.g. in combustion research, environmental flows, multiphase applications and process-engineering. These extensions of DNS and LES are illustrated in the contributions, while an ongoing interest remains with sophisticated modeling and numerical approaches, paying attention to physical, mathematical and engineering aspects.
