The length of the flame was shortened by the superposition of DBD, indicating the activation of combustion chemical reactions with the help of the plasma. In addition, we observed the modulation of the top position of the unburned gas region and the formations of local minimums in the axial distribution of the optical emission intensity of OH. These experimental results reveal the oscillation of the rates of combustion chemical reactions as a response to the activation by pulsed DBD. The cycle of the oscillation was 0.18-0.2 ms, which could be understood as the eigenfrequency of the plasma-assisted combustion reaction system.IOP Publishing2016-08engjournal articleAMhttp://hdl.handle.net/2115/66316https://doi.org/10.7567/JJAP.55.0862010021-4922Japanese Journal of Applied Physics (JJAP)558086201https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/66316/1/RP160196.pdfapplication/pdf1.17 MB2016-08
