| Outline of Final Research Achievements |
This work proposes a concept of a novel fire extinguish methodology applicable to any specialized fire (e.g., metal power fire, fire in highly the enclosed environments) via quick removal of firing matter as well as fume gas utilizing the vacuumed operation. Beyond of the existing fire-fighting strategies, such as, spraying inert gas or fire extinguisher to suppress the flame, the proposed methodology has several merits: 1) damaged area spraying fire-extinguisher can be limited, 2) extinction procedure can be effectively operated in the controlled chamber, 3) fume gas can be also extracted to enable the quick recovery. We firstly justify how this methodology works through the unique test facility developed for this purpose. Vacuuming timing is well-controlled to discuss the extinction behavior effectively. It turns out that there are three distinctive modes for extinction due to the vacuum operation and corresponding three non-dimensional groups can be identified.
