Review of Plasma Assisted Combustion Technology by Nanosecond Pulsed Discharge
摘要
Abstract
As a promising technology,plasma assisted combustion technology by nanosecond pulsed discharge (NPD) is capable of performing ignition and flame stabilization in engines,raising combustion efficiency while reducing emissions.Over the last decade,significant achievements have been made in the understanding of interaction mechanisms between NPD plasma and combustion,the effect of a variety of parameters on plasma assisted combustion,and its applications in the engine combustor through the design of some smart experiments,the use of advanced optical diagnostics and numerical simulation methods.In view of these facts,a brief history and the requirements of NPD plasma assisted combustion are presented at first.Then,three aspects including the combustion enhancing theory,experimental and applications studies,and diagnostics together with simulation technologies,are reviewed.Among them,several kinds of representative experiments under low/atmospheric pressure and middle/high pressure conditions are analyzed in detail,respectively,based on the magnitude of gas pressure as it is one of the most important parameters for gas discharge.Researches on some new applicable fields of plasma assisted combustion by NPD,such as ultra-lean burn,low temperature oxidation/combustion,mild combustion,and combustion instability control,are also introduced and discussed.Finally,considering the practical utilization of NPD plasma assisted combustion,future challenges and development tendencies are revealed.关键词
