摘　　要：本文建立了涉氢实验室三维模型,基于Fluent对氢泄漏后的扩散行为进行仿真模拟,旨在优化现场氢气探测器布局,改善通风条件,此外,还计算了氢气探测器响应后泄漏至实验室房间内的氢气总量,然后建立了以爆炸超压和距离为指标的氢泄露严重程度的定量评估方法,为涉氢场所的抗爆设计提供理论依据。A three-dimensional model of a hydrogen laboratory was established by this paper,and the diffusion behavior after hydrogen leakage was simulated using fluent.The aim was to optimize the layout of on-site hydrogen detectors and improve ventilation conditions.And the total amount of hydrogen that has leaked into the laboratory room after the response of the hydrogen detector was calculated,and a quantitative evaluation method for the severity of hydrogen leakage based on explosion overpressure and distance was established,providing a theoretical basis for the anti explosion design of hydrogen related places.
