摘要
基于计算流体力学对化工企业实验室氢气泄露进行模拟,研究了泄露速度和通风口直径对氢气泄露扩散的影响。结果表明:实验室氢气泄露以射流初始扩散,泄露过程中上浮扩散,空间内形成旋涡,泄漏源附近室顶区域属于最危险区域,氢气泄露速度越快,泄漏口直径越大,其在实验室区域内扩散越快,危险程度越高。
In this paper,computational fluid dynamics was used to simulate hydrogen leakage in the laboratory of chemical enterprises,and the influence of leakage speed and vent diameter on hydrogen leakage and diffusion was studied.The results show that the hydrogen leaks in the laboratory are initially diffused by jets.During the leak process,the hydrogen floats up and diffuses,forming vortices in the space.The area on the roof near the leak source is the most dangerous area.The faster the hydrogen leakage rate,the larger the diameter of the leakage opening.Then the faster hydrogen diffuses in the laboratory area,the higher the degree of danger.
