Electric field measurement in electric-field modified flames [PDF]

Proceedings of the Combustion Institute, 2021
Abstract The application of an electric field to a flame modifies the flame characteristics due to the collective motion of charged particles generated within the flame. The applied field mobilises electrons and ions depending on their polarity, leading to localised regions of space charge with sufficient density to either locally amplify or shield ...
