W/Oエマルション液滴のミクロ爆発による二次液滴飛散挙動に及ぼすベース燃料の影響

抄録

An experimental study has been performed by observing emulsion droplet behavior and secondary droplet behavior, and by measuring the emulsion droplet temperature. The emulsion was W/O (water-in-oil) type, the base fuels were n-dodecane, n-tetradecane and n-hexadecane. In this study, the effects of base fuel were mainly examined. When the boiling point of base fuel increased, the waiting time for disruptive micro-explosion was be shortened, and the droplet temperature just prior to disruptive microexplosion increased. The scattering velocity of secondary droplet had certain relationship with total waiting time for disruptive microexplosion.
