Abstract

The high spectral brightness of tunable high power excimer lasers allows the two-and three-dimensional application of techniques like laser-induced fluorescence (LIF), Mie and Rayleigh scattering for industrial applications. The construction of these lasers allows easy transportation and installation to perform measurements at combustion facilities which can not be moved. In combination with suitable filters and gated image-intensified CCD cameras techniques are now available to measure multi-dimensional distributions of temperatures and concentrations. Simultaneous measurements of temperature fields and hydroxyl radical distributions were performed to study the influence of turbulence on large premixed natural gas flames. A combination of temperature and nitric oxide concentration measurements yielded information about the correlations between NO formation and burner design in domestic gas burners. LIF and Mie scattering of fuel and hydroxyl radicals were used for measurements in IC engine simulators, Otto and Diesel engines.
