The Daniel Guggenheim School of Aerospace Engineering Presents

a talk by

Senior Scientist - Institute of Combustion Technology of the German Aerospace Center

About the Lecture
The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt, DLR) has led an effort in recent years to bridge the gap between fundamental scientific studies of combustion dynamics and system-level characterization of gas turbine combustors. This effort has focused on acquiring detailed measurements of well-defined turbulent flames in generic, swirl-stabilized combustors over a wide range of operating conditions, including at elevated pressure. These flames are designed to capture much of the complexity of a modern, swirl-stabilized gas turbine combustor, while maintaining excellent optical access for point- and planar laser measurement techniques.  This seminar will focus on the latest in this series of measurements, wherein high bandwidth laser imaging diagnostics (kHz acquisition-rate particle image velocimetry and planar laser-induced fluorescence) were applied simultaneously to study the effect of radial air-staging in a swirled combustor at 5 bars pressure.

About the Speaker

Dr. Isaac Boxx is a senior scientist at the Institute of Combustion Technology of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt – “DLR”) in Stuttgart. His research focusses on understanding the structure and dynamics of turbulent flames at engine-relevant conditions. Dr. Boxx is a pioneer in the development and application of high-bandwidth laser imaging techniques (kHz particle image velocimetry and planar laser-induced fluorescence) for the study of turbulent flames. These techniques have helped revolution our understanding of combustion instability, thermoacoustic pulsation, blow-off and flashback in gas turbine engines.

Prior to working at DLR, Dr. Boxx completed his PhD at the University of Texas at Austin and was a research associate with the Air Force Research Laboratory in Dayton, OH. His research is supported by the European Research Council, Air Force Office of Scientific Research and the German Aerospace Center.
