Experimental study has been carried out to obtain the detail information of the internal phenomena prior to occurrence of micro-explosion in a burning emulsion droplet using by 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 shows that the occurrences of internal boiling of emulsified water was observed prior to the occurrence of micro-explosion. The distribution function of occurrences of internal boiling was also obtained.
