| 中文摘要: |
| 本文分析了细雾水滴与浮升火焰羽流的相互作用,推导出雾滴在火场下降过程中的运动方程、汽化速率方程和热量衡算方程。采用龙格库塔差分方法,数值求解所得到的有关方程。利用数值解的结果探讨在给定火场条件下受限空间内细雾水灭火的临界水滴半径,并讨论了影响临界水滴半径的主要因素。 |
| 英文摘要: |
| 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. |
