Experimental measurements in high pressure combustion are challenging, especially in interpreting results in conditions with varying temperature and pressure state histories. These are the types of conditions that characterize modern and future combustion devices, which employ high pressure to improve efficiency and reduce pollutants. The high repetition rate shock tube is an excellent technique to probe these environments with advanced diagnostic techniques. In this presentation, I will discuss some recent experiments (absorption spectroscopy and ignition delay studies) in the high repetition rate shock tube which have encountered this varying state history challenge and the modeling methods to overcome them. Finally, I will discuss how these recent results with the miniature shock tube have motivated future projects in this area, including in analyzing highly exothermic reactions over wide pressure ranges and high throughput ignition delay measurements with new fuels.
Patrick Lynch is an assistant professor of Mechanical Engineering at University of Michigan-Dearborn, since 2013. He received his PhD in ME from the University of Illinois at Urbana-Champaign in 2010 and spent three years as a postdoctoral appointee at Argonne National Laboratory. His expertise and research interests are in high pressure combustion measurements, novel reactors and synchrotron sourced diagnostic techniques. He has built two miniature shock tubes, one at UM-D and another at ANL. Both have been used for laboratory as well as synchrotron sourced experiments He has published on the topics of metal combustion, optical techniques, high temperature chemical kinetics, and shock tube design, and to date has published 16 articles and numerous conference papers.
