This gif image particularly demonstrates a methane flame under the influence of electric field.  The electrical aspects of hydrocarbon flames contains amazing but complex nature that the flame geometry would be altered and experiencing this huge change. These images are first presented in May 2013 US National Meeting at Utah.  The full set of image is published in “Electric Field Induced Changes of Diffusion Flame and Heat Transfer near an Impinging Surface” (Energies – MDPI).
