Non-Intrusive, Reliable, and Portable Laser Induced Breakdown Spectroscopy for Instantaneous Gas Composition and Density Measurements in High-Speed Flows
Abstract
The proposed work aims to develop a flexible and portable n-LIBS fuel-air sensor for accurate gas property measurements in high-speed compressible reacting flows. The nanosecond laser induced breakdown spectroscopy (n-LIBS, Fig. 1) has been developed and used for monitoring gas composition and density in several research projects led by Dr. Campbell D. Carter [1-6]. These previous works have mostly investigated supersonic combustion phenomena targeting applications in supersonic combustors; some of the projects were carried out in collaboration with the PI of this proposed research project, Hyungrok Do, supported by 2012 – 2014 ASEE (American Society for Engineering Education) Air Force Summer Faculty Fellowship Programs, AFRL (Air Force Research Laboratory), and AFOSR (Air Force Office of Scientific Research).
