摘　　要：简要分析了气液两相流在柴油机燃油系统中的产生机理及带来的影响。介绍了柴油机燃油系统内气液两相流的研究现状,重点阐述了两相流中声速的计算、喷油规律的探索等,但现有研究较少对其流型进行识别。对现有的气液两相流流型识别方法进行了深入的分析和比较,并就柴油机燃油系统中气液两相流流型识别方法提出了建议,指出柴油机燃油系统中气液两相流流型的识别将会是未来研究的趋势之一。The generation mechanism and influence of gas-liquid two-phase flow in Diesel fuel system were briefly analyzed.The research status of gas-liquid two-phase flow of Diesel fuel system was introduced,sound velocity calculation and fuel injection discipline were particularly emphasized.But it was found that few studies were focused on its flow regime identification.Comparison and analysis were carried out on existing methods of flow regime identification,and suggestions were given to identify the flow regime of Diesel fuel system.Finally,this paper points out that the flow regime identification of gas-liquid two-phase flow in Diesel fuel system may be one of the research trends.
