项目摘要
This study was conducted for the establishment of understanding and generalizing spray diffusion combustion, which is commonly used in variety of combustion systems. Study was made for the two major topics : (1) combustion similarity, and (2) air-entrainments in spray flames. Here combustion similarity means that flow pattern and flame distribution develop similarly in differently sized combustion systems.The possibility of combustion similarity in differently sized spray combustion engines was theoretically investigated based on the analysis of governing equations of diffusion combustion. Because of this theoretical background, heat release rates and thermal efficiency can be predicted from scale model experiments. Based on an analysis of NO formation and the wall temperature of the combustion chamber, an algorithm to predict emissions and thermal loads were established. An experiment was then performed to compare predictions based on scale model experiments and results with large engines. The results showed good agreement with the theoretical predictions. Three dimensional computer simulation of combustion also supported the scale model experiments.Next theoretical formulation and its experimental validation for air entrainment changes in fuel spray combustion were performed. THe theory predicts air entrainment changes for a variety of swirl speeds, numbers of nozzle holes, nozzle diameters, engine speeds, injection speeds and fuel densities. Experiments were performed in order to compare theoretical predictions and experimental results in variety size of engines. All results showed good agreement with the theoretical predictions for shallow-dish piston engines.The study provides understanding of spray diffusion combustion and theories which are applicable for design and development of combustion systems.
本研究的目的是建立对喷雾扩散燃烧的理解和概括,喷雾扩散燃烧是一种常用的燃烧系统。本文主要研究了两个问题:(1)燃烧相似性;(2)喷雾火焰中的空气流动。燃烧相似性是指不同尺寸的燃烧系统中的流态和火焰分布发展相似,本文在分析扩散燃烧控制方程的基础上,从理论上探讨了不同尺寸喷雾燃烧发动机燃烧相似的可能性。由于这一理论背景,热释放速率和热效率可以从比例模型实验预测。在分析NO生成和燃烧室壁温的基础上,建立了预测排放和热负荷的算法。然后进行了一项实验,以比较基于比例模型实验和大型发动机结果的预测。计算结果与理论预测吻合较好。三维燃烧计算机模拟也为缩比模型试验提供了支持。其次,对燃油喷雾燃烧中空气卷吸量的变化进行了理论推导和试验验证。该理论预测了不同涡流速度、喷孔数目、喷孔直径、发动机转速、喷射速度和燃油密度时空气卷吸量的变化。在不同尺寸发动机上进行了试验,以比较理论预测和试验结果。计算结果与理论计算结果吻合较好,为进一步研究喷雾扩散燃烧提供了理论依据,为燃烧系统的设计和开发提供了理论依据。
