摘要:

提高内燃机热效率、降低燃烧室传热损失是实现动力系统节能降碳的重要途径。压燃发动机高压喷雾燃烧及火焰撞壁过程具有显著的非定常特征,局部壁面瞬态热流受喷射动量、燃烧放热、近壁湍流输运及火焰辐射共同影响,呈现复杂的时空非均匀性与历史依赖性。准确表征其传热规律及物理机制,是发动机热负荷预测与高效热管理的重要基础。该文围绕喷雾火焰发展、近壁输运及瞬态热流响应,系统综述压燃发动机撞壁喷雾火焰的传热特性、实验诊断方法及预测模型。首先,分析喷射条件、环境参数及壁面特性对局部瞬态热流的影响,讨论对流与辐射传热的动态演化及其贡献;其次,比较快速响应热电偶、磷光测温、微机电系统(MEMS)薄膜传感器及光学诊断等方法的适用性,重点评述瞬态热流反演、对流与辐射分离及近壁流动表征技术;进一步,分析传统传热关联式、累积喷射特征速度及累积喷射动能模型的物理基础与局限性。现有研究表明,撞壁喷雾火焰的局部热流不仅取决于瞬时热力学状态,还与喷射历程及近壁湍流演化密切相关,表现出相对于燃烧放热的相位滞后及喷射结束后的持续传热特征。最后,从近壁多物理场同步诊断、非平衡瞬态传热建模、低碳与零碳燃料传热机制及局部热负荷调控等方面展望未来研究方向,为压燃发动机瞬态传热预测与热管理优化提供参考。

Abstract:

Enhancing the thermal efficiency of internal combustion engines and minimizing heat transfer losses through combustion chamber walls are important ways to advance energy conservation and carbon emission reduction in power generation systems. In compression-ignition engines, high-pressure spray combustion and flame-wall interaction are highly transient processes. The local wall heat flux is affected by spray momentum, combustion heat release, near-wall turbulent transport, and flame radiation, resulting in complex spatial and temporal variations and dependence on flow history. Accurately characterizing these heat transfer processes and their physical mechanisms is essential for predicting engine thermal loads and improving thermal management. This paper systematically reviews the heat transfer characteristics, experimental diagnostic methods, and predictive models of wall-impinging spray flames in compression-ignition engines, focusing on spray flame development, near-wall transport, and transient wall heat flux. Firstly, the effects of injection conditions, ambient conditions, and wall properties on local transient heat flux are discussed, together with the evolution and contributions of convective and radiative heat transfer; secondly, the applicability of fast-response thermocouples, phosphor thermometry, micro-electro-mechanical systems (MEMS)-based thin-film sensors, and optical diagnostics is compared, emphasizing on transient heat flux reconstruction, separation of convection and radiation, and near-wall flow characterization; further, the physical basis and limitations of conventional heat transfer correlations, cumulative injection characteristic velocity models, and accumulated injection kinetic energy models are analyzed. Current research indicates that the local wall heat flux of impinging spray flames depends not only on the instantaneous thermodynamic state but also on the injection history and the development of near-wall turbulence, leading to a time lag between combustion heat release and wall heat flux, as well as sustained heat transfer after the end of fuel injection; finally, the future research directions are prospected from aspects such as simultaneous diagnostics of multiple near-wall physical fields, non-equilibrium transient heat transfer modeling, heat transfer mechanisms of low-carbon and zero-carbon fuels, and local thermal load control, providing references for the prediction of transient heat transfer and thermal management optimization of compression ignition engines.

Key words: compression-ignition engine, wall-impinging spray flame, transient wall heat flux, convection and radiation, characteristic velocity, accumulated injection kinetic energy
