摘要

为明确直流电场对燃烧的作用机理

在常温、初始压力100 kPa下

向定容燃烧弹内的网状电极加载3种电场

分别为两侧同为负直流电场、同为正直流电场以及左侧为负直流电场右侧为正直流电场

研究3种电场加载方式下的直流电场对甲烷/空气预混火焰燃烧特性的影响。结果表明:在3种电场加载方式下

火焰形变、平均火焰传播速度、压力峰值随着电压的增大均增大; 当电压幅值相同时

两侧同为负电场对火焰促进效果最强

其次为左侧为负电场右侧为正电场

两侧同为正电场对火焰促进效果最弱。由模拟计算可知:电体积力随着电压的增大而增大

两电极同为负电场与正电场时

平均火焰传播速度增大率和电体积力之间的相关系数分别为0.996、0.997

压力峰值增大率和电体积力之间的相关系数分别为0.989、0.971

说明电体积力与电场对火焰的促进作用密切相关; 当电压幅值为10 kV时

两电极同为负电场与正电场的离子风发展程度分别为0.153、0.019

说明正是由于离子风发展程度的不同导致了正负电场对燃烧促进作用不同。

Abstract

To investigate the effect of DC electric field on the combustion characteristics

experiments were conducted under the condition of normal temperature and initial pressure of 100 kPa

and electric field was applied on the mesh electrodes within the combustion bomb in three ways: applying negative DC electric field on both sides; applying positive DC electric field on both sides; and applying negative DC electric field on the left side and positive DC electric field on the right side. The methane/air premixed flame combustion characteristics were studied under the three kinds of electric fields. The results showed that the flame deformation

average flame propagation velocity and pressure peak all increased with the increase of the loading voltage. When the voltage amplitude was the same

the negative electric field applied on both sides had the strongest promotion effect on the flame

followed by the negative electric field on the left side and positive electric field on the right side
