Abstract

In subsonic turbulent combustion, laser techniques such as laser velocimetry, laser-induced fluorescence (LIF), Raman scattering, and Mie scattering have been applied extensively. Point measurements using these techniques have given time and spatially resolved measurements of temperature, species concentration, mixture fraction, and velocity. UV Raman scattering probes using the KrF excimer laser are being developed for measurement of supersonic flows. In addition, two-dimensional (2D) imaging has been developed using LIF and Raman scattering to detect flow field properties. These techniques can be readily applied in supersonic flows to obtain statistical information on the supersonic combustion.
