Abstract

A plasma-enhanced combustion dome is developed based on the gliding arc discharge technology in areo-engine combustors, and the effect of the gliding arc plasma on fuel spray performance at different discharge voltages is studied through fuel spray performance experiments. The application of the gliding arc plasma fuel pyrolysis technology shows that the fuel molecules of high-carbon chains are broken into small molecules of low-carbon chains under the impact of high-temperature electrons, leading to decrease in viscosity and increase in atomization performance of the fuel. With the rise of the discharge voltage, the atomization angle of the fuel increases, the SMD average value of fuel atomization decreases, and the uniformity of fuel atomization is improved. When the inlet air flow is 20 m³/h and the excess air coefficient is 0.6, the atomization cone angle of the fuel spray without applying plasma excitation is 43°, the average SMD 93.545 6 μm and the non-uniformity coefficient 0.304. When the discharge voltage reaches 200 V, the atomization cone angle of the fuel spray increases to 75°, the average value of SMD is reduced to 89.690 6 μm, and the non-uniformity coefficient drops to 0.233.
