为探究不同频率交流电场助燃的内在机制,利用定容燃烧试验平台比较了低频(40、60、80、100 Hz)和高频(15、20、25、30 kHz)交流电场对甲烷/空气稀薄燃烧(过量空气系数为1.2、1.4、1.6)火焰的影响,并利用机器学习方法对混合气的燃烧特征参数进行了预测研究。结果表明:低频和高频交流电场下,火焰在电场方向上均被拉伸,不同频率交流电场对火焰传播的促进效果处于同一量级,但低频交流电场下的火焰锋面更加稳定;高频交流电场对燃烧特性参数的影响更加显著,其对应的压力峰值和压力升高率峰值均比低频交流电场下变化更大;采用支持向量机方法构建的平均火焰传播速度和燃烧压力峰值的预测模型相关系数均高于0.998
平均绝对百分比误差和希尔不等系数分别小于1.093%和0.007
均具有良好的预测性能和泛化能力。研究进一步验证了低频和高频交流电场的助燃机制,证实了机器学习方法应用于基础燃烧特征参数预测的可行性,丰富了电场助燃理论。
