【摘要】 本文论述了应用激光全息摄影技术对柴油喷雾场的粒度分布所进行的测量。定量地揭示了喷射压力、喷孔直径、介质密度、燃油喷射量及喷孔流量系数等因素对喷雾场分布和油粒平均直径的相互关系。从而建立起一个喷雾场油滴尺寸分布的瞬态经验计算模型,并同国外学者的工作进行了对比。更多还原

【Abstract】 This paper discusses the measurements of the droplet size distributionof the diesel spray by applying the laser holographic technique,which re-veals the correlations between such factors such as injection pressure,ori-fice diameter,ambient gaseous density,the quantity of the fuel deliveryand orifice flow coefficient and those of the size distribution,themean diameter of spray droplets,thereby establishes an instantaneous em-pirical calculation model of the spray droplet size distribution.Compar-isons are being made with similar results obtained by foreign scholars.更多还原
