Abstract : 45 SCIENTISTS AND ENGINEERS FROM 7 COUNTRIES PARTICIPATED IN THE Flameless Combustion workshop that was sponsored by Dr. Gabriel Roy of ONR. During the two and half days workshop that took place in Lund, Sweden, on June 19-2 1, the foremost experts in this new field of research, reviewed experimental, computational, and modeling investigations on this topic. Representatives from industry, academia, and government agencies provided their perspectives regarding this emerging technology. The workshop concluded by extensive discussions on the technology state-of-the-art and future roadmap. Flameless Combustion is characterized by high stability levels with virtually no thermoacoustic instabilities, very low lean stability limits and therefore extremely low NOx production, efficient and rapid oxidation of CO in the distributed flame, and a unifdrm temperature pattern factor at the combustor exit The high oxidizer temperature requirement makes Flameless combustion well suited for the more thermodynamic efficient high pressure ratio propulsion and power systems that have high compressor discharge temperatures. These characteristic ofFlameless Combustion are very desirable characteristics for future gas turbine engines and for advanced ramjet propulsion. The proceedings of the workshop are available on CD and the final manuscripts will be published in a book.
