| Outline of Final Research Achievements |
In flooding, low-lying streets and underpasses are common sites of accidents with submerged cars. In the case flooding is severe, cars are floated and flushed away. We executed two main research activities on car problems, namely, (1) experiment study of evacuation from a partially submerged car, and (2) experiment study of incipient floating motion of car in flooding.
(1)Evacuation experiments were conducted by using a real-size car model. A small minivan with a slide type rear door was used. The experimental results indicate that the water depth of about 0.75 m is the critical evacuation condition through the slide type door. (2) The critical incipient condition was studied experimentally, using the 1/10 and 1/18 scale car models. On the base of experimental results, we could draw the diagram of critical incipient condition of real car by both flow velocity and water depth. Sedan typed cars are likely to be floated if the flow velocity exceeds 2m/s and the water depth exceeds 0.5m.
