Dynamic behaviours of a flame as plasma in a strong electric field

Abstract Dynamic behaviours of a flame are experimentally examined via applying an electric potential difference between two parallel electrodes and placing a flame of ethanol between them. Given that a flame behaves as a weakly ionised plasma, the shape of the flame is affected by an external stron...
