This paper presents a novel method based on electrostatic sensing to measure the flicker frequency of a hydrocarbon flame. The flame flickering behaviour is determined by measuring the concentration changes of ions in the flame and characterized by processing the signals from an electrostatic sensor.

Power spectral analysis of the sensor signals is performed to obtain their frequency components. Experimental tests were conducted on a laboratory-scale combustion test rig for different equivalence ratios. Flame images were simultaneously acquired using a high-speed camera to provide a direct comparison between the results from the electrostatic sensors and those from the imaging approach. It is found that the flickering frequency of the burner flame decreases with the equivalence ratio. The results obtained demonstrate that the electrostatic sensing method can measure the flickering frequency of the flame and is useful for the assessment of flame stability.

An optical fibre system was applied to capture simultaneously the flame flickering at two different light frequencies nm and nm , which provided a means of comparing the chemistry change. It was found that the low frequency oscillation of flow and flame structures depended only weakly on the exit velocities of the fuel, while ambient conditions had a significant effect on flickering frequencies and spectrum.
The results of using CH 4 and C 3 H 8 as test fuels at different flow rates showed very little variations, with peak frequencies at 11—13 Hz. When the jet flame was not disturbed, harmonics to at least the third mode were obtained in most of these cases. Mechanisms thought to produce changes in the dynamic response and frequency harmonics were discussed.
