Note (General): The present document summarizes the different experiments done on active control by using chemiluminescence measurements. First a brief introduction on the chemical mechanisms that are responsible for chemiluminescence in hydrocarbon flames is presented together with simulations for lean cases. Detailed discussion and limitations of inverse Abel transform to estimate the planar distribution of the chemiluminescence is shown, and effects of absorption and geometrical optics are discussed. A brief presentation of the two different combustors is done followed by a detailed explanation of the results obtained with chemiluminescence. Three different chemiluminescence techniques are used, namely spatially, spectrally and temporally resolved techniques. All those three approaches prove to be useful to characterize the oscillating mechanisms occurring in premixed combustors. Imaging techniques are used to show the regions where strong coupling between pressure and heat release exist. Spectrally resolved techniques are used to discuss the nature of the flame (from premixed to non fully premixed) and to obtain an estimate of the equivalence ratio through emission ratio between OH* and CH* emissions. Finally, temporally resolved techniques can be used to detect onset of oscillatory combustion using combined pressure-chemiluminescence product or through an analysis in the frequency domain (coherence) to understand the frequencies at which coupling between pressure and heat release occurs. Conclusions are drawn and emphasizes for future investigations are addressed.
