| 摘 要： | 内燃机喷雾模拟计算结果对选用的初级破碎模型、次级破碎模型有较强的依赖性。每个模型的仔细确认成为成功分析和优化柴油机和汽油机高压喷雾的主要条件之一。本文主要讨论了内燃机CFD软件中的多种喷雾破碎模型,从中可看出,喷雾初级破碎模型受到了越来越多的重视。

| Abstract: | The accuracy of the ICE spray calculation results depends on the models adopted for simulation of the(primary) and secondary breakup process.Hence,careful validation of the individual breakup models serves as an important prerequiste for the successful analysis and the optimization of high pressure sprays in diesel as well as in gasoline engines.The main spray breakup models used in CFD are mainly discussed in this paper. |
