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 P~1500 W. This work is part of a project to apply time reversal to create the plasma in a further study. The results presented here will be used for the following of the project.
