Outline of Final Research Achievements

This research gave results mentioned below for the following two sub-topic.
1. In case of "the suppression of ignition of combustible material by water application", The experiments using the system constructed by electoric heater, water application system and combustible material were carried out. In these experiments, ignition time et. al. were measured under various heating and sprinkling conditions. From the analysis and consideration of these experimental results, an estimation model for ignition time considering the cooling effect by water applicaiton were suggested.
2. In case of "the suppression of flame propagation of combustible interior finish by water application", the experiments that water application activated at the time when the combustible material ignited from the bottom was propagating were carried out. In these experiments, the surface temperature and heat release rate of combustible interior finish was measured.
