질소충진 비누방울을 이용한 소화기법에 관한 연구

다국어 초록 (Multilingual Abstract)

The transient behavior of liquid film and the flow of inner gas by bursting of the soap bubble and the fire extinguishment by a soap bubble capsule filled with nitrogen gas were investigated in this paper. To visualize the transient behavior of the soap bubble after rupturing, a pulse laser was used for contactless rupturing of the soap bubble. And then, to visualize the fire extinguishment by a soap bubble capsule, a candle was used for rupturing of the soap bubble by fire. After rupturing of soap bubble, the inner gas flew out through the hole of crack and two different kinds of gas flow were formed. The primary flow was generated by the pressure difference between the inside and outside of the soap bubble. The secondary flow was generated by the liquid soap film dynamics in the soap bubble bursting. Combined, these flows of nitrogen gas extinguished the fire.
