氢气爆燃条件下安全壳结构完整性分析OA

This paper mainly makes a simulation study on the safety under the condition of hydrogen deflagration,and obtains the spatial distribution and time evolution characteristics of the pressure field and temperature field in the containment when hydrogen deflagration occurs under different working conditions.The complete and credible pressure and temperature load data acting on the inner wall and inside the containment during hydrogen deflagration are obtained,so as to provide input parameters for the mechanical response analysis of containment and equipment.The simulation results show that under the influence of high temperature and high pressure caused by hydrogen deflagration and detonation in the containment,the maximum deformation of the containment structure is 95.274 m and the maximum stress is about 2.6E+11 Pa,which is much larger than the yield limit of the structural steel used in the containment.The containment has undergone plastic deformation and the structure has been fundamentally destroyed.
