Wavelength-modulation spectroscopy for determination of gas properties in hostile environments
Abstract/Contents
- Abstract
- Over the past 40 years, tunable diode laser absorption spectroscopy (TDLAS) sensors have matured into a practical technology for providing non-intrusive, in-situ measurements of gas properties in a number of hostile energy systems. However, the applicability of TDLAS sensors has been limited by a number of fundamental measurement challenges including: beam-steering, non-absorbing transmission losses, interfering emission, line-of-sight non-uniformities, and broad and blended absorption spectra at high pressures. This work presents the development and demonstration of several novel calibration-free wavelength-modulation spectroscopy (WMS) techniques and sensors that enable high-fidelity measurements of gas properties in highly non-uniform gases and high-pressure gases. These WMS techniques are demonstrated with measurements of gas temperature, H2O, pressure, and velocity in two model scramjet combustors and a pulse detonation combustor.
