Turbulent multiphase combustion plays an important role in both nature (e.g., volcanos and pool fires) and industry (e.g., industrial furnaces, aeroengines, and internal combustion engines). It is a highly complex multiscale and multi-physicochemical process in which interactions between the dispersed and continuous phases, phase change, droplet collisions, evaporation, mixing, heat transfer, and chemical reactions occur simultaneously. In recent years, significant progress has been made in understanding the mechanisms of spray flames and their behaviors in combustion engines. This paper covers key and representative developments in the area of turbulent spray combustion with a focus on spray–chemistry–turbulence interactions. The effects of turbulence–chemistry, spray–turbulence, and spray–chemistry interactions on the spray process, ignition, flame stabilization and emission are comprehensively discussed at elevated pressures and temperatures. Furthermore, spray–radiation and spray flame–wall interactions, which are important to engine performance and emission characteristics, are scrutinized. Supercritical spray flames and turbulent spray flames in dual-fuel engines are also discussed. Finally, outlooks and further challenges for the research field are outlined.

类似发动机条件下的喷雾-湍流-化学相互作用

湍流多相燃烧在自然界(例如火山和池火)和工业(例如工业炉、航空发动机和内燃机)中都起着重要作用。它是一个高度复杂的多尺度和多物理化学过程,其中分散相和连续相之间的相互作用、相变、液滴碰撞、蒸发、混合、传热和化学反应同时发生。近年来,在理解喷射火焰的机制及其在内燃机中的行为方面取得了重大进展。本文涵盖了湍流喷雾燃烧领域的关键和代表性发展,重点是喷雾-化学-湍流相互作用。湍流-化学、喷雾-湍流和喷雾-化学相互作用对喷雾过程、点火、在升高的压力和温度下对火焰稳定和排放进行了全面的讨论。此外,对发动机性能和排放特性很重要的喷雾-辐射和喷雾火焰-壁相互作用进行了仔细检查。还讨论了双燃料发动机中的超临界喷射火焰和湍流喷射火焰。最后,概述了研究领域的前景和进一步的挑战。
