Paper Abstract

High-temperature water vapor imaging based on Raman scattering for hypersonic exhaust diagnostics has been developed. A temperature-independent UV Raman line imaging instrument that is calibrated with room air and readily scaled to large combustion facilities has been tested in a laboratory H2/air combustor. The H2O concentration measurements exhibit a single-shot standard deviation of approximately 8%. In this paper we investigate practical issues concerning the application of UV Raman line imaging for quantitative water vapor measurements.
