Paper Abstract

Laser diagnostic techniques play an important role in combustion research. Four laser-based measurement techniques are developed for harsh combustion environments. In the measurements of aeroengine turbine combustor, two dimension temperature distribution of a interior cross-section was obtained by self-designed 2D-scan coherent anti-stokes Raman scattering (CARS) system, and the main species concentration in the region above the primary hole were measured by spontaneous vibration Raman scattering (SVRS). In the investigations of a supersonic combustor, the line-of-sight averaged temperature was on-line acquired by tunable diode laser absorption spectroscopy (TDLAS) technique, and the velocity components near the exit of combustor were obtained by single line hydroxyl tagging velocimetry (HTV). These measurement activities demonstrate that laser diagnostic techniques have well performance in harsh environments, such as unclean combustion, strong vibration and high background emission. These diagnostic techniques can provide useful experimental data for validating computational fluid dynamics (CFD) model and evaluating combustor characteristics.
