Abstract:
The recently developed Laser Raman and Laser Doppler techniques may be ideally suited for the diagnostics of combustion. Both techniques are nonintrusive and essentially supplementary. However, under certain conditions the spontaneous Raman diagnostics may fail, due to excessive noise, unwanted fluorescence and other sources of interference. In order to alleviate these difficulties, and attempt has been made to use the CARS diagnostic method. In this paper, after a review of the above-mentioned diagnostic techniques, some experimental results, and some data processing methods are discussed, which permit the extraction of turbulent information from spontaneous Raman scattering. These are compared to turbulent data as obtained from L.D.V. Author
