Fuel ignition using remote generation of microwave plasma in air at atmospheric pressure

Abstract

The high demand for a new ignition device for aeronautical engines has motivated the study on an innovative microwave approach, presented in this paper. A dedicated experimental set-up is presented in which we demonstrate the successful ignition of a kerosene spray by a remotely excited microwave plasma. This plasma is created in a Split Ring Resonator (SRR) gap, placed in a copper cavity, in air at atmospheric conditions at the frequency of f = 2.8467 GHz and a pulsed power injected into the cavity of Pcav ≈ 1500 W.
