| Outline of Final Research Achievements |
In order to clarify the flame spreading mechanism of Tsunami fires, the combustion phenomena formed over a liquid fuel have been investigated experimentally. Two different kinds of flame spreading experiments were performed. One was the flame spreading formed over a liquid floating on a still water layer. The other was the opposed-flow flame spreading formed over a liquid fuel stream. As a result, it is seen that the spreading rate of the flame formed over still fuel and water layers becomes lower than that of the flame formed over a fuel layer. On the other hand, it is found that the spreading rate of the flame formed over the opposed fuel flow increases as the opposed fuel flow speed becomes larger. However, when the fuel flow speed is much larger than the flame spreading rate, the flame was flowed downstream.
