N2 - In order to investigate the reason for the rapid combustion of diesel-benzyl azides blend droplets, the burning characteristics of diesel-benzyl azides droplets were studied by the free falling technique. The influence of oxygen concentration was also investigated. The results show that the benzyl azides droplets deform and explode during the middle and late burning periods, indicating that micro-explosion happens due to the liquid phase reaction of benzyl azides, which remarkably increases the burning rate. With increasing mass fraction of benzyl azides, the burning rate increases, the ignition delay decreases and the burning time increases. Meanwhile, the droplet combustion flame shape changes from the wake flame to the envelope flame, which means more sooting propensity. In addition, with increasing oxygen concentration, the ignition delay decreases, the burning time remarkably increases and droplets burn more completely.
