Abstract
To realize the rapid combustion, an experimental study of droplet vaporization characteristics of diesel-benzyl azides blend was conducted using the suspended droplet device. Morphological transformations of the droplet during the vaporization processes were monitored with a high-speed digital camera. The effects of ambient temperature on vaporization characteristics were also studied using a droplet with initial diameter of 1.42 mm. Experimental results showed that, droplet vaporization behavior of the blend was distinct from that of diesel. With increasing mass fraction of benzyl azides, the lifetime is shortened. Meanwhile, puffing and microexplosion were identified during droplet vaporization, such strong responses are believed to be caused by the rapid release of nitrogen due to decomposition of benzyl azides occuring in the liquid phase. In addition, with increasing the ambient temperature, micro explosion intensity of droplet was intensified, and this increased the vaporization rate.
