摘要
本文基于Fluent软件对于氨气储罐的泄漏进行模拟,研究在不同风速、不同风向以及设置障碍物下对氨气扩散的影响.研究表明,氨气在自然扩散时呈蒲扇形沿着风向扩散;风速越大氨气在水平风速方向上扩散距离越远,污染范围也越大;风向与氨气泄漏口位置水平垂直时,氨气首先垂直于风向扩散一定距离,然后再沿水平风向扩散;障碍物对氨气的扩散速度和范围具有阻碍作用.
This paper uses Fluent software to simulate ammonia leakage diffusion and ananlyze the fluence of ammonia leakage diffusion under different of wind speed,wind direction and barrier. Results show that ammonia diffuse as the cattail leaf fan following the wind;the ammonia diffusion distance increase with the wind speed increased and the range of pollution also increase;when wind direction is perpendicular to the leak,firstly,ammonia diffuse some distance perpendicular to wind direction,and then diffuse following wind direction;the obstacle have the function of discourage to the speed and range of ammonia leakage diffusion.
