ZS1110直喷柴油机喷雾及混合气形成过程的三维数值模拟

Three-dimension Numerical Simulation of Spray and Mixed-gas Formation process in Model ZS1110 DI Diesel Engine

利用移植到微机上的KIVA程序对常柴ZS1110直喷式柴油机的喷雾及混合气形成过程进行了三维数值模拟，并用数值模拟的方法探讨了喷油嘴喷孔直径不一致时对混合气浓度分布的影响，计算结果为该机的改进提供了充分的理论依据。

Three-dimension numerical simulation has been applied to thespray and mixed-gas formation process in Model ZS1110 DI diesel engine withthe program modified from KIVA. Numerical simulation has been used to research the effect of different spray nozzle diameters on the distribution of themixed-gas. The results give the theoretical evidence for modifying the engine.
