为了引起我国对非平衡等离子体燃料强化技术研究的重视并促进该技术的发展,介绍了脉冲电晕放电和介质阻挡放电产生的非平衡等离子体对燃料或者可燃混合气活化作用的基本原理和特点,综述了国内外研究现状,并展望了其应用前景。
The development of non-thermal plasma combustion enhancement technology is reviewed. The effects of activation of fuel or fuel-air mixtures by electrical non-equilibrium discharges on their combustion properties including ignition, combustion rate and stability are discussed. The principal role of processes with formation of excited components that support the development of the chain mechanism of oxidation of fuel is presented. Pulsed corona and dielectric barrier discharges are investigated with respect to their suitability for plasma ignition and combustion enhancement respectively. Results show that this kind of technology can be applied in propulsion and engines, particularly, internal combustion engines operation under lean-burn conditions and pulse detonation engines.
