Advanced Combustion and Aerothermal Technologies NATO Science for Peace and Security Series This Series presents the results of scientific meetings supported under the NATO Programme: Science for Peace and Security (SPS). The NATO SPS Programme supports meetings in the following Key Priority areas: (1) Defence Against Terrorism; (2) Countering other Threats to Security and (3)NATO, Partner and Mediterranean Dialogue Country Priorities. The types of meeting supported are generally "Advanced Study Institutes" and "Advanced Research Workshops". The NATO SPS Series collects together the results of these meetings.The meetings are co- organized by scientists from NATO countries and scientists from NATO's "Partner" or "Mediterranean Dialogue" countries.The observations and recommendations made at the meetings, as well as the contents of the volumes in the Series, reflect those of parti- cipants and contributors only;they should not necessarily be regarded as reflecting NATO views or policy. Advanced Study Institutes (ASI) are high-level tutorial courses intended to convey the latest developments in a subject to an advanced-level audience Advanced Research Workshops (ARW) are expert meetings where an intense but informal exchange of views at the frontiers of a subject aims at identifying directions for future action Following a transformation of the programme in 2006 the Series has been re-named and re-organised. Recent volumes on topics not related to security, which result from meetings supported under the programme earlier, may be found in the NATO Science Series. The Series is published by IOS Press, Amsterdam, and Springer, Dordrecht, in conjunction with the NATO Public Diplomacy Division. Sub-Series A. Chemistry and Biology Springer B.

Turoff PREFACE The NATO Advanced Workshop “Advanced Combustion and Aerothermal Technologies: Environmental Protection and Pollution Reductions” was held in Kiev (Ukraine) from 15 to 19 May 2006 and was organized by the Institute of Engineering Thermophysics (Ukraine) and Cardiff University (UK). This Workshop based on the long-term collaboration between the Institute of Engineering Thermophysics and Cardiff University resulted in a first NATO Scientific Prize received by Professor N. Syred, UK, and Professor A. Khalatov in 2002, who served as Workshop codirectors. The justification for this Workshop was based upon the perceived need for the bringing together of research in a number of combustion and aerothermal- related areas, so as to allow more rapid progress to be made. The primary Workshop objectives were to assess the existing knowledge on advanced combustion and aerothermal technologies providing reduced environmental impact, to identify directions for future research in the field, and to promote the close relationships and business contacts between scientists from the NATO and partner countries. This synergy in research and development is essential if advances in specific areas are to be widely utilized, whilst helping to cross- fertilize other areas and stimulate new developments. Of especial importance is the dissemination of concepts and ideas evolved in the aerospace industries into other related areas, whilst encouraging contacts, research exchanges, and inter- actions between engineers and scientists in the NATO and partner countries. The Workshop program included keynote lectures, oral and roundtable discussions; the subjects addressed were as follows: • A critical review of the use of swirling, cyclonic and vortex flow for stabilization of high-intensity flames and associated problems • A critical review of the use of computational fluid dynamics (CFD) and advanced numerical modeling • A review of the application of advanced diagnostics to flames and high- temperature systems • A critical review of advances in gas turbine technologies and what directions future work needs to take • Clean combustion of alternative fuels for industrial gas turbines • Circulating fluidized beds for solid fuel combustion • Minimization, utilization, and energy recovery from wastes • Improvements to drying technologies through application of advanced combustion technologies • Multifluid models of turbulent combustion • Fuel cell power generation ix x PREFACE These carefully chosen subjects were felt to cover the critical areas of combustion and aerothermal research and development where rapid progress is needed to improve performance in terms of efficiency, compactness, and emissions. This was a very timely and successful Workshop which brought together experts from the NATO and other countries to discuss increasing concerns about emissions. The dramatic increasing price of fuels over the last 5 years means that every effort has to be made to spread best practice and cross-fertilize as many areas as possible for mutual benefit. The editors take pleasure in acknowledging the cooperation and involvement of the NATO Science Committee, who have made this workshop possible. The outstanding work of the publishers, Springer, removed much of the onus for author and editor alike in the preparation of this book. Finally, we express our profound gratitude to the authors of the individual papers, who have worked so competently and conscientiously to provide this extremely important collection.
