An experimental study was performed to investigate the correspondence between fluctuating ion density, light emission and acoustic emission in open premixed, turbulent propane/air flames. To date the kinds of measurements employed have been a) pointwise, cross section average and volume average of the ion density fluctuation, b) cross section average and volume average of the C/sub 2/ radical light emission fluctuations and c) the far field acoustic pressure fluctuations. It is shown that the measurements may be interchanged so that they are all indicators of the same quantity-heat release rate fluctuations. 10 refs.
