Three-dimensional simulation of ionic wind in a laminar premixed Bunsen flame subjected to a transverse DC electric field

摘要: Abstract The role of the ionic wind effects on modifying flame dynamics was demonstrated by detailed computational models. Full three-dimensional simulations were conducted to reproduce and describe response a laminar premixed methane–air Bunsen subjected transverse DC electric field at saturation condition. chemical kinetic mechanism employed skeletal with an optimized ionization model predict positive negative ions that are important for generating currents. Given strong dependence amount charged species created chemi-ionization, ion production rate match measured current. simulation successfully reproduced tilt toward cathode. winds blowing from electrodes in both rightward leftward directions also captured. calculated flow is qualitatively consistent PIV experimental data. Accurate description three-body electron attachment oxygen charge transfer reactions heavy anions found be critical simulating flame–electric interaction. This first demonstration effect full simulations. Further investigation experiment modeling required future work address quantitative differences.
