摘要
对柴油机燃油雾化过程进行了简要分析,并简单介绍了喷雾数值计算基本思想和喷雾模拟中应用较多的各种物理模型的类型及特点,详细说明了喷油器内部燃油流动对后续喷雾过程造成影响的原因。同时对目前常用的ELSA喷雾模型不同算法的特点进行了分析比较,并对未来喷雾模型的发展方向进行了展望。
The atomization process of diesel engine is analyzed in this paper. Different physical models and their characteristics, the reason for the nozzle internal flow influence on fuel atomization process are also introduced. The comparison of different algorithms of ELSA spray model is discussed. A perspective view of spray model in the future is presented.
