| Research Abstract |
Secondary atomization behavior was observed by a high-speed video camera with shadow imaging method. As a result, puffing and micro-explosion behaviors of spray droplets around 50 mm were clearly visualized. Visualization shows that secondary atomization significantly improves spray characteristics. Moreover, large dispersed water droplets improved the intensity of secondary atomization and provided a finer spray flow. The initial size of the dispersed water droplets played an important role in the spray characteristics of the emulsified fuel spray.
