不同频率高频交流电对球形传播火焰的影响

摘要/Abstract

摘要： 摘要：为研究不同频率高频交流电场对预混稀燃火焰的影响，对常温、常压下定容燃烧弹中过量空气系数为1.6时的甲烷/空气火焰的传播和燃烧特性进行了研究.结果表明：高频交流电场作用下，火焰均在水平方向被拉伸，当加载交流电压有效值一定时，交流电频率越高，火焰在水平方向的拉伸越剧烈.与未加载电压相比，当交流电压有效值u=5 kV,交流电频率f为5、7.5、10、12.5和15 kHz时，平均火焰传播速度分别提高43.10%、53.45%、63.79%、74.14%和84.48%，相对燃烧压力增大率的最大值分别为0.15、0.21、0.27、0.36和0.50.由此得出，高频交流电场对火焰燃烧有一定的促进作用，且交流电频率越高，促进作用越明显.

Abstract: Abstract： An experiment was conducted under a lean combustion condition to investigate the influences of highfrequency alternating electric fields of different frequencies on the flame propagation and combustion characteristics of premixed CH4/air mixtures at an excess air ratio of 1.6, room temperature and atmospheric pressure. The results show that the flame is stretched horizontally when a highfrequency alternating electric field is applied to the electrodes. When the voltage virtual value is invariable, the flame stretches more severely with the frequency increasing. Compared with those without the applied voltage, when the voltage virtual value is 5 kV and the frequencies are 5, 7.5, 10, 12.5 and 15 kHz, the average flame propagation speed increases by 43.10%, 53.45%, 63.79%, 74.14% and 84.48%. The maxima of the increase rate of relative combustion pressure are 0.15, 0.21, 0.27, 0.36 and 0.50, respectively. These results indicate that highfrequency alternating electric fields are beneficial to the flame combustion and as the frequency increases, the promoting effect also increase.
