不同气象条件下液氨储罐泄漏扩散伤害范围预测研究

Forecasting the Damage Range of Liquid Ammonia Storage Tank Leakage Diffusion in Different Meteorological Conditions

为研究不同气象条件下液氨储罐泄漏伤害范围,有效控制和降低事故的后果,以渭南某化工企业液氨储罐为研究对象,对其不同气象条件下泄漏的扩散规律进行仿真模拟和数值分析。首先运用MATLAB模拟软件,采用高斯羽流模型,确定不同条件下液氨储罐的泄漏扩散危险区域。然后采用Origin软件,对不同气象条件下泄漏扩散造成的最远伤害距离进行拟合预测。

For researching the damage range of liquid ammonia storage tank leakage diffusion under different meteorological conditions, to control and reduce the accident consequences effectively, taking the liquid ammonia tank of chemical industrial in Weinan as the object. Under different meteorological conditions, ammonia storage tank leakage diffusion law was simulated. Firstly, using the MATLAB simulated software, according to Gaussian plume model, to get the liquid ammonia tank leakage diffusion dangerous areas. And then, using Origin software and according the curve smoothly fitting method, to forecast the farthest injury distance of liquid ammonia storage tank leakage diffusion in different meteorological conditions.
