摘　　要：阐述了闪急沸腾喷雾的基本原理,通过比较分析闪急沸腾喷雾与传统喷雾的差异,指出闪急沸腾喷雾是一种极具潜力的燃油喷射方式;论述了近年来国内外对过热燃油和溶气燃油闪急沸腾喷雾研究的进展与现状,介绍了过热液体闪急沸腾喷雾的数学模型及其发展,并从理论上分析了影响闪急沸腾喷雾的因素;展望了闪急沸腾喷雾的应用前景以及进一步研究的发展方向。The basic principles of flash boiling spray was introduced and it was indicated that the flash boiling spray was a great potential way for fuel injection by analyzing the difference between the flash boiling spray and traditional spray. The progress and status of study on flash boiling spray of superheated fuel and fuel containing dissolved gas at home and abroad in recent years were reviewed. The mathematic model of flash boiling spray for superheated fuel and its development were also introduced and the factors of affecting flash boiling spray were theoretically analyzed. Finally, the application prospect and development trend for further research of flash boiling spray were pointed out.
