摘　　要：喷雾模型是内燃机CFD软件中重要的组成部分,而喷雾模型是由多种子模型组成的。正确设定喷嘴出口的边界条件和选择恰当的喷雾子模型成为成功分析和优化柴油机和汽油机高压喷雾的先决条件。本文主要讨论了喷嘴流动模型、液膜雾化模型和喷雾碰壁模型在CFD软件中的应用现状。The spray model is a main part in the CFD software of IC engine, the careful validation of all the sub-models and the availability of proper boundary conditions at the injector exit serve as the major prerequisites for the successful analysis and optimization of high pressure sprays in diesel as well as in gasoline engines. In this paper, the nozzle flow model, the sheet model and the spray-wall interaction models are mainly discussed.
