Experimental study has been carried out to reveal the interacting effect of the onset of micro-explosion in the combustion processes of emulsion droplet array. Detail measurements of waiting time for onset of micro-explosion are made for base fuels f n-hexadecane and n-dodecane, and water contents of 0.1 and 0.2. The fuel in water emulsion consisting base fuel and water doped with small amount of surfactant were tested after degasification. The results showed that the waiting time for the onset of micro-explosion in the droplet array were correlated to the Weibull distribution. It is found that the onset of micro-explosion is accelerated by the micro-explosion of an adjacent droplet. This interaction results in shortening the lifetime of the emulsion droplet array.
