三维旋转滑动弧等离子体助燃激励器的光谱特性实验
An Experiment of Spectral Characteristics on Plasma-assisted Combustion with 3D Rotating Gliding Arc Discharge
摘要
Abstract
In view of studying the spectral characteristic laws of plasma-assisted combustion with 3D rotating gliding arc discharge under different jet flow and voltages, three kinds of electrodes (A, B, C) withdifferent geometrical structures are investigated upon its spectral signalsof gliding arc discharge plasma alternating current under atmosphericpressure.The results demonstrate that the vibrational temperaturesbecome higher with increase of jet flow and voltage, that is, vibrational excitation intensity becomes fiercer during discharging.Simultaneously, compared with the gliding arc discharge plasma spectral characteristics of another two electrodes, A with higher vibrational temperature of plasma during discharging is the best one to actuate the plasma.In consideration of factors mentioned above, the influence of flow rates onthe vibrational temperature is the most obvious.The larger the flow rate triggers, and the stronger the relative emission intensity of particles such as OH, O2 and O.For instance, the average emission intensity of O isabout 1 800 a.u.unit under 40 g/min (U0=120), and as the flow increasesto 100 g/min, the average emission intensity of O enlarges to 2 800 a.u.unit.关键词
