摘要:
为了研究海上风电氢一体化能源系统水下输氢管道小孔泄漏气体扩散问题，基于流体力学计算软件，建立近海水下输氢管道泄漏扩散模型，考虑复杂水体流动，对不同水深、流速条件下的泄漏气体扩散行为进行模拟与分析，研究水下气体泄漏扩散行为、上浮时间以及水面扩散影响范围等因素。研究结果表明：水下气体泄漏呈羽流状，随水流向下游方向偏移，在水面上浮形成一定范围的扩散沸腾区域；泄漏气体初始动能快速衰减，上浮时间主要受到水深的控制；水流对气体羽流存在明显的偏移现象，且与流速呈正相关关系，同时也会增加水面扩散影响范围；构建基于水流速度与泄漏源深度的水面扩散泄漏参数多元非线性预测方程，能够较好地预测泄漏发生后的水面关键参数。研究结果可为我国近海风电储氢一体化体系建立与事故应急处置提供理论支撑。
Abstract:
In order to study the gas diffusion problem of small hole leakage in underwater hydrogen pipeline of offshore wind power and hydrogen integrated energy system,a leakage and diffusion model of offshore underwater hydrogen pipeline was established by using the fluid dynamics calculation software.Considering the complex water flow,the leakage group diffusion behavior under different water depths and water flow velocities was simulated and analyzed,and the factors such as underwater gas leakage and diffusion behavior,floating time and influence range of water surface diffusion were studied.The results show that the underwater gas leakage is plume-like,which shifts with the downstream direction of water flow,and a certain range of diffusion and boiling area is formed on the water surface.The initial kinetic energy of the leakage gas decays rapidly,and the floating time is mainly controlled by the water depth.There is the obvious deviation phenomenon of water flow to gas plume,and it is positively correlated with water flow velocity,which also increases the influence range of water surface diffusion.A multivariate nonlinear prediction equation of water surface diffusion and leakage parameters based on the water flow velocity and leakage source depth is constructed,which can better predict the key parameters of water surface after leakage.The research results can provide a theoretical basis for the establishment of offshore wind power and hydrogen storage integrated system and accident emergency response in China.
