摘要
氢作为可再生能源,清洁环保、利用率高且来源广泛,但氢气易燃易爆的高风险性使其难以拓展应用,以位于内陆河的氢燃料电池船为例,使用PHAST、FLACS软件建立35 MPa储氢罐体模型并进行CFD模拟与数值分析,以泄漏位置、泄漏孔径、温度和压力等变量作为主要计算条件,模拟船舶停靠及加注过程中的潜在危险场景,对事故进行分析,通过二维与三维结合的方式得出氢气泄漏、爆炸和热辐射事故的影响范围,并在此基础上提出降低风险的具体措施,对未来氢燃料电池船储氢罐与船用加氢站安全管理提供重要参考.
Abstract
As a renewable energy source,hydrogen is clean,environmentally friendly,highly utilized and widely available.However,the high risk of hydrogen flammability and explosion makes it difficult to expand its applica-tion.Taking the hydrogen fuel cell ship located on the inland river bank as an example,the 35 MPa hydrogen storage tank model is established by using PH AST and FLACS software,and CFD simulation and numerical anal-ysis are carried out.Taking variables such as leakage location,leakage aperture,temperature and pressure as the main calculation conditions,the potential dangerous scenarios in the process of ship docking and filling are simulated,and the accidents are analyzed.The influence range of hydrogen leakage,explosion and thermal radi-ation accidents is obtained by combining two-dimensional and three-dimensional methods.On this basis,specif-ic measures to reduce risks are proposed to provide important reference for the safety management of hydrogen storage tanks and marine hydrogen refueling stations on hydrogen fuel cell ships in the future.
