在这项工作中，闪急沸腾的液体破碎和雾化的影响，首先审查，然后详细描述了两个多流股汽油直接喷射器工作与罗恩-95汽油在120巴和200巴的压力，燃料喷射持续时间为0.8毫秒到低于大气压的压力之间的1和0.1巴和温度之间的20°C和100°C。喷雾被注入光学访问室中，该室的温度和压力独立控制。应用具有单次拍摄CCD相机的米氏成像以获得在上述条件的矩阵下的喷雾的图像。为了研究锥角对流与流相互作用的影响，使用了两种不同的喷射器，一种具有60度的标称外锥角，另一种具有90度的标称外锥角。纸张ID ILASS 08 -6-1
In this work the effect of flash boiling on liquid breakup and atomization is first reviewed and then described in detail for two multistream gasoline direct injectors operating with RON-95 gasoline at 120 bar and 200 bar pressure with a fuel injection duration of 0.8 ms into sub-atmospheric pressures between 1 and 0.1bar and temperatures between 20°C and 100°C. The sprays were injected into the optically accessed chamber whose temperature and pressure were independently controlled. Mie imaging with a single shot CCD camera was applied to obtain images of the sprays under a matrix of the above conditions. In order to investigate the influence of the cone angle on the stream to stream interaction, two different injectors were used, one with a 60 degree and the other with a 90 degree nominal external cone angle.
