摘      要：This paper discusses the flowing process inside a nozzle, especially the formation mechanism of cavitations within the nozzle and puts forward a nozzle flow model, which takes account of the injection conditions and nozzle geometry. By the model being implemented to the KIVA codes, the spray characteristics (e. g., spray penetration and cone angle) of diesel and dimethyl ether (DME) are simulated. The comparisons between the computational and experimental results are performed, which show that the liquid spray characteristics could be more truly demonstrated by considering the existence of the cavitations. Key words nozzle model - spray characteristics - cavitation - atomization CLC number O 35 - TK 402 Foundation item: Supported by the National Natural Science Foundation of China (50376018) and the National 973 Basic Research Program of China (2001CB209207) Biography: WEI Ming-rui (1967-), male, Associate professor, Ph.
