为探究涡扇炮扑救储油罐火灾的效能及作用机制，构建复合燃烧体系，通过多维度热电偶阵列和热辐射监测网络，分析灭火过程中温度场与热辐射场的演变规律。结果表明：涡扇炮驱动下细水雾与氟蛋白泡沫的协同作用可实现高效灭火，形成了“降温-窒息-隔离”协同机制；细水雾在相变吸热阶段产生40℃/s的极速降温，氟蛋白泡沫形成持久封闭层，协同作用下49 s内完全扑灭火场。试验证明了涡扇炮在扑救储油罐立体火、流淌火时具有显著优势。

In order to explore the effectiveness and mechanism of turbofan cannons in extinguishing oil tank fires, a composite combustion system was constructed. Through a multidimensional thermocouple array and thermal radiation monitoring network, the evolution of temperature field and thermal radiation field during the fire extinguishing process were analyzed. The results show that the synergetic effect of water mist and fluoroprotein foam, driven by the turbofan cannon, can achieve efficient fire extinguishing, forming a "cooling-asphyxiation-isolation" synergetic mechanism. The water mist produces a rapid cooling of 40 ℃/s during the phase change and heat absorption stage, and the fluoroprotein foam forms a durable sealing layer, which can completely extinguish the fire within 49 s under the synergetic effect. Therefore, turbofan cannons have significant advantages in extinguishing three-dimensional and flowing fires in oil storage tanks.
