摘要
针对安全科学与工程专业灭火类课程的教学需求,研发了细水雾灭遮挡火实验装置,并耦合了先进的激光流场诊断系统。依托该实验装置,设计了细水雾雾特性表征、细水雾灭遮挡火效能评价以及OH自由基的浓度分布测量等探究性实验项目。通过系列教学实验,学生可直观观察细水雾在不同条件下的灭火过程,掌握获取相关特征参数的测量手段,从而加深对细水雾灭火机理的理解,提升实验技能和创新能力。
Aiming at the needs of fire suppression courses teaching in the specialty of safety science and technology,an experimental apparatus was developed for studying water mist in extinguishing shielded fires,in combination with advanced laser diagnostic systems for flow fields.Based on the apparatus,a series of exploring experiments were designed,including properties characterization of water mist,performance evaluation of water mist in extinguishing shielded fires,concentration distribution measurement of OH radicals in the flame,etc.Through experimental teaching,the students could directly observe the fire suppression process of water mist in varied conditions and master the methods for measuring related specific parameters.Therefore,they could get a deeper understanding of the extinguishing mechanism of water mist and achieve improvements in experimental skills and creativity.
