摘要：

To verify the feasibility of improved lean-fuel combustion performance of aviation kerosene with plasma assistance, a cylindrical plasma-assisted combustion actuator (PACA) using dielectric barrier discharge (DBD) was designed to conduct the validation tests of plasma-assisted combustion (PAC) of lean-fuel aviation kerosene. The impact of plasma excitation parameters including duty ratio of power supply, feedstock gas flow rate, and applied voltage on combustion performance including combustion efficiency and weak limit of combustion stability was analyzed and the results were compared with normal combustion of lean kerosene-air mixture without plasma assistance. The preliminary reason that plasma enhances combustion performance of lean aviation kerosene was also analyzed. Experimental results show that the decrease of duty ratio of power supply or feedstock gas flow rate, as well as the increase of applied voltage leads to the increase of combustion efficiency and expansion of weak limit of combustion stability, and combustion performance is improved to some extent when plasma-assisted combustion excitation is applied. The main factor that plasma enhances lean-fuel combustion performance of aviation kerosene is the generation of O3 during DBD's air plasma discharge in cylinder PACA. © 2016, Editorial Department of Journal of Propulsion Technology.
