利用激波与森林的作用,有可能成为森林灭火中的一项新技术。本文报告了激波与林带作用的实验模拟方法、实验技术与装备、测试和显示手段等基本技术环节。激波在林地、林带中的传播和衰减,以及其它物理现象由纹影方法作了显示。激波诱导的压力场也作了测量。研究表明,以激波管为基础的模拟技术是成功的,实验结果对于进一步认识激波与林冠火阵面的相互作用有很好的先导意义。
The use of shock waves and forests can potentially become a new technology in forest fire suppression. This paper reports on the basic techniques of experimental simulation of shock wave and forest band, experimental techniques and equipment, testing and display methods. Shock waves in woodlands, forest belt propagation and attenuation, and other physical phenomena by the shadow method was shown. The shock induced pressure field was also measured. The research shows that the shock tube-based simulation technique is successful and the experimental results are of great significance for further understanding the interaction between the shock wave and the canopy fire surface.
