## Description

 Title: Absorption Spectroscopy In The 4.4-4.6 Μm Infrared Wavelength Range For The 10 Khz High-speed Measurement Of Co And Co2 Concentrations In Combusting Environments. Author(s): Fotia, Matthew L. Contributor(s): Schauer, Fred; Hoke, John; Sell, Brian C. Subject(s): Analytical, Combustion, Plasma Abstract: An instrument has been developed to make 10 kHz \textit{in situ} combustion gas measurements of carbon monoxide ($CO$) and carbon dioxide ($CO_2$) concentrations. Operating in both the 4.40 and 4.58 $\mu m$ wavelength ranges allows for the fundamental molecular absorption bands of both molecules to be utilized.\\ Such concentration measurements allow for the determination of total combustion efficiency of a particular process, which has engineering implications when considering the energy available from a combustion process to be utilized for propulsion purposes.\\ A brief discussion of the initial calibration of the sensor with a calibrated diffusion flame, Hencken burner, and pressure-concentration cell is made with the main focus of the current work being the application of the instrument to examine the structure of propagating detonation waves.\\ Issue Date: 2014-06-16 Publisher: International Symposium on Molecular Spectroscopy Citation Info: Fotia, M.L.; Schauer, F.; Hoke, J.; Sell, B.C.
