Pulsed Current-Voltage-Induced Perturbations of a Premixed Propane/Air Flame
Figure 7
CH chemiluminescence images showing a comparison of flame structure for a Φ = 1.1, m/s flame with no voltage (left), +2.7 kV applied voltage, and the resultant CH chemiluminescence intensity plot (right). Note the local reduction in flame height and a 16% increase in CH chemiluminescence intensity due to disturbance in the middle of the flame. Image is rescaled to highlight the high intensity regions. Region of interest used for CH intensity plot is shown on the left.
