摘要:
针对液化石油气球罐泄漏扩散问题,基于计算流体动力学软件FLUENT,参照某型号球罐,建立球罐的三维模型。模拟得到LPG的泄漏扩散分布规律,并根据LPG的1.5%(φ)～9.5%(φ)爆炸极限确定LPG泄漏后的危险区域。模拟结果得出LPG泄漏扩散的规律并以此预测LPG泄漏扩散危险区域。为此类事故的预防、控制以及人员应急逃生等提供了参考。 

Abstract:
In order to study the leakage and diffusion of LPG spherical tank, a three-dimensional model of spherical tank by taking a spherical tank as reference, was established based on a computational fluid dynamics software FLUENT. The danger zone after the leakage of natural gas was determined according to LPG explosion limit of 1.5%-9.5%. Simulation results showed that the leakage and diffusion laws of LPG and further the danger zone of the leakage and diffusion of LPG could be predicted based on these factors. This paper provided a reference for the prevention, control and emergency escape of similar accidents.
