| 摘 要： | 为探究海上浮式生产储油卸油船(floating production storage and offloading，FPSO)爆燃事故加强机制，采用计算流体力学(computational fluid dynamics, CFD)对FPSO爆燃事故进行数值模拟。模拟结果表明，在拥塞度较大的钢架结构区域，火焰速度和爆燃压力急剧增大。为进一步探究复杂钢架结构和管系对爆燃事故的加强机制，搭建半开敞管道甲烷 空气爆燃实验系统。实验结果表明，在爆燃过程中复杂钢架结构和管系能够诱导火焰产生强烈的湍流作用，加快未燃气体的燃烧速度，导致爆燃事故后果加强。结合数值模拟结果与实验结果，为FPSO爆燃事故防治给出建议。

Analysis on strengthening mechanism of FPSO deflagration accidents |
| |
| Abstract: | In order to explore the strengthening mechanism of floating production storage and offloading (FPSO) deflagration accidents, FPSO deflagration accidents are simulated numerically by computational fluid dynamics (CFD). The simulation results show that the flame speed and the deflagration pressure increase sharply in the area of steel frame structure with larger congestion. In order to further explore the strengthening mechanism of the complex steel frame structure and pipe system on deflagration accidents, a semi open pipeline methane air deflagration experimental system is built. The experimental results show that in the process of deflagration, the complex steel frame structure and pipe system can induce the flame to produce strong turbulence, accelerate the combustion speed of unburned gas, and lead to the strengthening of the consequences of deflagration accidents. Combined with numerical simulation results and experimental results, some suggestions for FPSO deflagration accident prevention are given. |
