Direct numerical simulation of a turbulent methane/air flame impinged by a sub-breakdown electric field

The effects of an external electric field on a turbulent methane/air diffusion flame are analyzed in this work using direct numerical simulations. configuration consists temporally evolving mixing layer air and mixture methane nitrogen at 1 atm that is impinged by the direction normal to mean plane. combustion chemi-ionization reactions involved flow modeled finite-rate chemistry reduced reaction scheme consisting 26 species 134 reactions. mass ion-wind detailed description coefficients mobilities based kinetic theory. presented calculations show turbulence generated within mostly unaffected applied for under exam. In fact, body force developed away from region where uniform. Conversely, able introduce very high intermittency electrically charged concentration and, consequently, force. Such will constitute challenge future formulation models take into account effects.
