Influence of Electric Field on Flame Characteristics
Electric field-assisted combustion is the utilization of an external electric field to segregate charged particles into monopolar regions, generating ion-driven winds that propel surrounding neutral substances. This mechanism is often regarded as a potent flame control strategy and a crucial means to enhance fuel combustion efficiency. The present study extensively investigates flame characteristics, carbon particle emissions, and simulation scenarios under various forms and application methods of electric fields. The research consolidates the varying degrees of errors resulting from different methods of measuring flame parameters, as well as the role of refined numerical simulations in predicting experimental data. The findings underscore the prevalence of two-dimensional simulations in the current landscape, necessitating the development of accurate three-dimensional models to simulate and predict flame behavior under electric fields. Furthermore, the research highlights the dearth of measurement outcomes for different fuels under electric fields at elevated pressure and temperature conditions, aiming to facilitate the broader and more precise development of kinetic and chemical models for flames in electric fields.
