摘要： 喷射流量与喷射时间是评估以全氟己酮为代表的新型高沸点气体灭火系统灭火效率的核心参数。本文针对高沸点灭火剂喷放过程中的复杂气液两相流特性，系统对比了涡轮流量计、热式质量流量计及科氏力质量流量计的适用性，并通过实测分析确定涡轮流量计为最优测量方案，同时结合理论分析与试验验证，建立了喷射停止节点的物理判定准则，实现了喷射起止时刻的客观界定。该测量方法兼具高精度与普适性，可适用于不同系统结构与工况，具有显著的经济效益与工程指导价值。研究成果可为新型气体灭火系统的性能评价、设计优化及标准制定提供关键技术支撑。

Abstract: The discharging flow rate and time are the core parameters for evaluating the fire suppression efficiency of new high-boiling-point gas fire suppression systems, such as those based on FK-5-1-12. This paper focuses on the complex gas-liquid two-phase flow characteristics during the discharging process of high-boiling-point fire suppressants, systematically comparing the applicability of turbine flowmeter, thermal mass flowmeter, and Coriolis mass flowmeter. Through actual measurement analysis, it is determined that the turbine flowmeter is the optimal measurement scheme. At the same time, combined with theoretical analysis and experimental verification, the physical determination criteria for the discharge stop point are established, achieving the objective definition of the start and stop times of the discharge. This measurement method has both high accuracy and universality, and can be applied to different system structures and operating conditions, with significant economic benefits and engineering guidance value. The research results could provide key technical support for the performance evaluation, design optimization, and standard formulation of new gas fire suppression systems.
