Non-thermal Ignition of Premixed Hydrocarbon-air and co-air Flows by Nonequilibrium RF Plasma

Initiation of diffusion combustion in a supersonic flow of H2–air mixture by electrical-discharge-excited oxygen molecules

“…The possibilities of promoting combustion by an electrical discharge have been widely discussed in the past decade. Different plasma-assisted approaches to intensify the ignition and combustion such as heating the mixture by an arc or plasma torch [1,2], the production of highly reactive radicals and atoms by electron impact dissociation [3,4] and the excitation of vibrational and electronic states of molecules in a specially arranged electrical discharge [5][6][7] were proposed. The latter one is the most promising from the standpoint of low temperature combustion initiation and the least energyconsuming method.…”

Characteristics of Gliding Arc and Its Application in Combustion Enhancement

“…Over the course of the last few decades, much research has been focused on supersonic combustion development and has brought our understanding a long way closer to a tangible and reliable system. Many solutions have been realized in this regard, ranging from passive cavity flame holders [1][2][3][4][5] to energy addition via precombustors [6][7][8] and plasma [9][10][11][12][13][14][15][16][17], to combat the aforementioned problems in supersonic flow systems. Cavities or ramped cavities provide a subsonic region for flame stabilization as well as enhanced mixing, but do not add any energy to the system, setting an upper limit on the extent of enhancement.…”

Control of combustion by generation of singlet oxygen molecules in electrical discharge

“…Different plasma-assisted approaches to enhance the combustion such as the heating the mixture by spark discharge or plasma torch [1,2], the production of highly reactive radicals and atoms by electron impact dissociation [3,4], and the excitation of internal degrees of freedom of molecules [5,6] have been considered. The latter one is the most promising (from the standpoint of affecting the initiation of combustion) and the least energy-consuming method.…”
