| Abstract: | This paper has analysed the interaction of water mists with buoyant flame on the fire site. When water mists are falling through the buoyant gas and flame, the equations are established theoretically to describe their motion, heat balance and the evaporating rate. The original spraying speed of water drops, the velocities of the buoyant gas and flame, and the height of the flame in the confined space have been considered. Then, the numerical solutions to the equations are obtained by means of Rouge\|Kutta's difference method. Finally, the main factors that influence the critical radii of the water drops are discussed using the solutions. |
