摘要 为了研究整个放电时间内助燃等离子体中活性粒子浓度随时间的变化情况,在建立空气放电等离子体动力学零维模型的基础上,对空气放电进行数值模拟研究,分析了放电频率对空气放电等离子体中的活性粒子浓度变化的影响。结果表明:随着电压频率的增加,放电时间间隔减小,活性粒子衰减时间缩短,活性粒子浓度增加。 To research the evolvement characteristics of plasma-produced species enhance com-bustion with discharging time ,this article carries on a numerical simulation of evolution laws of the main particles in air plasma with time-variation under air plasma dynamic model and analyzes the in-fluence of discharge frequency on evolvement characteristics of air plasma .The results show that the distance of discharge time and radicals attenuation time reduce lead to radicals concentration increased with frequency increase .
