摘要
示踪平面激光诱导荧光技术是将分子原子示踪方法与平面激光诱导荧光技术相结合,可获得燃料分布、混合度、组分浓度、局部当量比等流场信息,具有非扰动、时空分辨率高、实时原位测量、可定量、灵敏度高等优势,适用于发动机燃料掺混相关研究。本文综述了示踪平面激光诱导荧光技术的原理、测量方法,着重阐述了其在不同发动机测量应用的进展,并分析了该方法的优点与局限,同时对其未来发展进行展望。
Tracer-based planar laser-induced fluorescence technology,which integrates molecular/atomic tracer methods with planar laser-induced fluorescence techniques,enables the acquisition of flow field information,including fuel distribution,mixing uniformity,component concentration,and local equivalence ratio.Characterized by its non-intrusive nature,high spatiotemporal resolution,real-time in situ measurement capability,quantitative capability,and superior sensitivity,this technique is particularly applicable to research on fuel mixing processes in engine systems.The paper not only summarizes the principles and measurement methods of tracer plane laser-induced fluorescence technology,but also discusses its applications in different engine measurements.Finally,this paper systematically evaluates the technique's advantages and current limitations,while proposing potential advancements for its application in future research.
