电场对火焰特性的影响
摘要:电场辅助燃烧是利用外部电场，通过将带电物质分离到单极区域来产生离子驱动的风，从而驱动周围的中性物质，这通常被认为是一种强大的火焰控制机制，是提升燃料燃烧效率的一个重要手段。对不同形式、不同施加方式的电场下的火焰特性、碳烟颗粒的排放和仿真现状进行广泛研究，总结不同火焰参数测量方式导致的不同程度的误差，及完善的数值模拟对实验数据的预测作用。结果表明：当前的数值模拟大多是2维的，需要开发完善准确的3维模型来模拟和预测火焰在电场下的特性；也需要在高压力和温度条件下对不同燃料在电场下的测量结果，以便在电场下为火焰开发出更广泛、更精确的动力学和化学模型。
Abstract：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.
