Abstract

<p>Fire extinguishment by water mist has been researched because it doesn't damage electronic equipments like sprinkler and water doesn't harm the environment like Halons. First, we researched the flow field and motion of water mist without pool fire. From the results, we found that water mist spread horizontally by vortex induced by drag force between water mist and ambient gas. Next, we researched motion of single droplet and motion of water mist and a contribution to fire extinguishment in the flow field with pool fire. Water mist must reach a base of flame before evaporating in order to extinguish fire so that single water droplet and water mist were set away from a flame axis in order to avoid the effect of updraft induced by pool fire. The results revealed that motion of single water droplet differs from that of water mist and the effect of fire extinguishment depends on the initial location of water mist. The farther from a flame axis the initial location is, the weaker the effect of fire extinguishment is.</p>
