Abstract
Experimental study has been carried out to obtain the detail information of the internal phenomena and disruptive burning in emulsion droplet combustion using by acoustic emission (AE) measurement. n-Hexadecane in water emulsion droplet, which was suspended at the tip of a quartz filament, was burning in a quiescent air environment. The filament is mounted at the center of sufficiently large cylindrical block. AE sensor was also mounted at the extension of the filament on the opposite side of the block. The results show that the occurrence of disruptive burning processes was detected by AE successfully. It is also was observed internal boiling of emulsified water prior to the occurrence of micro-explosion. The distribution function of occurrences of internal boiling was also obtained.
