Ignition by Electric Spark Discharges Triggered by the Fuel/Energetic Aerosol Itself
Abstract
In this project, electric breakdown triggered by the presence of non-conductive droplets is studied with experiment and simulation. The presence of droplets can lower the threshold for breakdown by a large extent. There are several modes to trigger spark by the presence of droplets: (1) electrospray from the deposited liquid on the electrode; (2) single droplet repelled from the deposited liquid moving toward the opposite electrode; (3) single droplet attracted to an electrode but then forming an electrospray; and (4) presence of a single droplet very close to an electrode. The mechanism for triggering of the spark is attributed to electric field enhanced by the presence of high dielectric-constant liquid. The presence of materials in-between the electrode may also hinder the spark because of the adhesion of the initial ions onto the surfaces of the droplets or particles.
