The simultaneous measurement of velocity and temperature in combustion flows by the combined use of a laser Doppler velocimeter (LDV) and coherent anti-Stokes Raman Spectroscopy (CARS) was studied. In order to avoid hostile surroundings in the combustion area, high power laser beams for CARS were sent to the test section over a distance of 44 meters by a pipe with corner mirrors. The LDV and CARS signals were sent back to the measurement room by fiber optics. Using a specific mirror, four beams for both the LDV and the CARS were focused onto the measuring point by a lens. The signals thus generated were passed through dichroic mirrors and interfero-filters. The coincidence of the LDV and the CARS signals was checked by the lag time between the two signals. Velocity-temperature correlations were given for turbulent flames behind a bluff-body flame stabilizer.
