摘　　要：　介绍了喷雾模型的类型、发展历史和最新进展,详述了多维工作过程模型中喷雾模型、数值计算方法,介绍了较具有代表性的KIVA系列程序中的喷雾模型,并对这一领域发展中存在的问题和未来的方向进行了探讨。Fuel Spray model is one of the most important parts of diesel engines'in-cylinder numerical simulations. Different types of spray model, the history and the latest progressin this field were introduced in this paper. And multi-dimensional spray models were compared indetail. Further more, the spray models in the most widely used CFD programs for multidimensional spray and combustion modeling-KIVA serial programs were emphatically introduced. The major subjects about modeling of diesel engine sprayand perspective methods in future were discussed.
