Summer School on Direct Numerical Simulation of Reacting and Two-Phase Flows

Summer School on Direct Numerical Simulation of Reacting and Two-Phase Flows

Berlin, Germany

September 2nd - 8th, 2007


General Information:

The Laboratory of Fluid Dynamics and Technical Flows of the University of Magdeburg "Otto von Guericke", the Technical University of Berlin, the ERCOFTAC Special Interest Groups SIG28 "Reactive flows" and  SIG12 "Dispersed turbulent two-phase flow" organise an International Summer School on the:

Direct Numerical Simulation (DNS) of Reacting and Two-Phase Flows,

from September, 2-8, 2007 in Berlin, Germany. This summer school welcomes all researchers from university and industry interested in the present potential and recent development of DNS methods for reacting and two-phase flows.  

Introduction:

Reacting and two-phase flows are found in a variety of practical systems (energy generation, propulsion, chemical engineering, meteorology....) but are still associated with many open theoretical questions. In many cases DNS are essential as a complement to experimental investigations in order to understand the basic coupling processes controlling complex flows. However, Direct Numerical Simulations have very specific, strict requirements, generally not widely known to students or researchers familiar mostly with the standard, Reynolds-averaged approach. Furthermore, the accurate numerical modelling of reacting and two-phase flows requires a variety of physical sub-models, which must be carefully chosen in order to obtain a reliable numerical description of real flows.

This Summer School will focus on the theory, implementation and choice of model in the DNS of reacting and two-phase flows and is intended for researchers as well as code developers (PhD students or R&D engineers) interested in understanding and implementing DNS methods, or simply in acquiring a better background on the topic in order to assess its possible contribution to real problem solving. The instructors are all experts in DNS, numerical methods, and associated physical models and will present not only the various models and methods most commonly employed but also implementation and efficiency issues ranging from basic principles to state-of-the-art applications. The course will have a duration of 5 days (full teaching programme) plus two days of get-together, in order to foster exchange and communication among participants, during and after the Summer School.  

Organizers and instructors:

  • Dominique Thévenin (Univ. of Magdeburg "Otto von Guericke", Germany; main organizer): DNS, in particular for reacting flows, as well as reduced Population Balance Models for dispersed two-phase flows.
  • Ananias Tomboulides (Univ. of Western Macedonia, formerly Aristotle Univ. of Thessaloniki, Greece: leader of SIG28 Reactive flows): numerical aspects of DNS of reacting flows, in particular using spectral-type methods, and low-Mach number vs. compressible formulations.
  • Martin Sommerfeld (Univ. Halle-Wittenberg "Martin Luther", Germany; leader of SIG12 Dispersed turbulent two-phase flow): fundamental aspects of multiphase flows, experimental and numerical studies, DNS of two-phase flows.
  • Frank Thiele (Technical Univ. Berlin, Germany; local organizer): Computational Fluid Dynamics and DNS, in particular concerning the development of appropriate numerical methods.

  • Bénédicte Cuenot (CERFACS, France): DNS and LES of turbulent flames, model development.
  • Michael Manhart (Technical Univ. Munich, Germany): DNS and LES of complex flows, in particular regarding chemical engineering applications and incompressible fluids.
  • Julien Réveillon (INSA Rouen, France): DNS and LES of two-phase flows, in particular regarding spray combustion.
  • Kai Sundmacher (Univ. of Magdeburg "Otto von Guericke", Germany): Population Balance Models for chemical engineering, application to emulsions and precipitation processes.

All lectures will be given in English; extensive notes and related documents will be distributed on a CD/DVD-ROM to all participants at registration.
