Simultaneous Temperature Measurements with Raman and CARS (Coherent Antistokes Raman Scattering) in Laminar Flames,
Abstract
Spatially resolved temperature measurements in laminar premixed flames were made using Coherent Antistokes Raman Scattering (CARS) and spontaneous Raman spectroscopy. In the case of narrowband (scanning) CARS, the experimental arrangement allows the performance of simultaneous temperature measurements with both techniques. For broadband (multiplex) CARS the measurements have to be made successively. Three different Raman linewidth models were used for CARS data evaluation. The results were compared with the independently recorded rotational Raman temperatures. Temperature differences up to 10% were observed, depending on the linewidth model used. For two, more complicated line-width models the CARS and Raman temperatures are in good agreement.
