Characterization of Lean, Turbulent Flames at Gas Turbine Operating Conditions Using Highspeed Laser-Diagnostic Techniques
Abstract
High bandwidth laser imaging demonstrated in turbulent swirl- and bluff-body stabilized flames at pressures of up to 20 bars. Detailed, multi- diagnostic measurements were acquired in swirl- and bluff-body stabilized flames at elevated pressures. These measurements generated significant new insight into the turbulent mixing and flame dynamics, combustion instabilities and flow-flame interaction. Three external measurement campaigns were completed at universities in the United States. During these campaigns, the research teams of young faculty (sponsored through the AFOSR-BCR program) received both hands-on training and valuable practical experience in the design, setup and operation of sophisticated laser diagnostic systems for combustion research. Research performed during this project has (at the time of writing) resulted in five peer-reviewed journal papers, with two more currently under review. Several more still in preparation. In addition, it has generated nine conference proceedings. Finally, the project also provided a unique, hands-on research experience in high bandwidth laser imaging for AFRL scientists Dr. Campbell Carter and Dr. Carrie Noren, who engaged in on-site research collaborations linked to the project.
