Experimental study has been carried out to obtain the detail information about the occurrence of micro-explosion in a burning emulsion droplet using by high speed visualization technique and acoustic emission (AE) measurement. A n-hexadecane in water emulsion droplet, which was suspended at the tip of a quartz fiber was burning in a quiescent air environment. The fiber was mounted at the center of sufficiently large cylindrical block. AE sensor was also mounted at the extension of the fiber on the opposite side of the block. The results indicate that the intensity of micro-explosion could be determined by the measured AE signals relatively. The distribution function of micro-explosion intensity was also obtained.
