邻舱火灾对弹药舱温度特性影响的数值研究

摘要

为获得邻舱发生火灾时对被研究弹药舱温度特性的影响,采用性能化消防设计的理念,通过计算机建立三维模型,运用大涡模拟技术的数值模拟方法对邻舱发生火灾时通过公共壁面导热对研究弹药舱舱室内的温度影响进行模拟,通过火灾动力学模拟模型软件进行计算机物理建模与仿真再现邻舱火灾场景,并对仿真结果参数数据进行处理,获得被研究弹药舱内各温度探测器测点处相应参数的实时数据、变化特性等,从而得到被研究舱室受邻舱火灾影响时的特性规律.该研究结果对弹药舱内的火灾早期探测与消防应对等具有一定的参考价值.%In order to get the influence on the temperature of the tested ammunition cabin when the adjoin-cabin have a fire, adopt the idea of performance-based fire protection design(PFPD), get the three-dimensional model by the computer, in-troduce the numerical simulation method which based on the large-eddy simulation technology to simulate the temperature effect of ammunition cabin, where in the temperature is effected because the hest is conducted by the public board when the adjoin-cabin have a fire, at the same time make use of the fire dynamic simulator (FDS) to reappear the scene of the fire in adjoin-cabin by the computer modeling and simulation, data processing the simulation result, get the real-time database and the change characters of the measuring point in the ammunition cabin, then study the temperature change regulation in the ammunition adjoin-cabin. The study result have reference value to the early fire detection and fire control of fire.
