摘要 利用流体力学Fluent软件,对液化石油气球罐区泄漏扩散进行了数值模拟,主要研究不同风速和不同形状障碍物存在条件下扩散流场的变化规律。结果表明:风速影响扩散方向、距离、浓度以及扩散平衡时间;障碍物的存在改变了常规扩散轨迹、空腔区浓度积聚,且不同曲率的障碍物在介质扩散过程中所承受的外压不同。该研究结果对球罐区安全事故救援具有指导意义。 This paper uses fluid mechanics software "Fluent" to simulate the leakage diffusion of liquefied oil in spherical tanks.The main research lies in the effects of different wind speeds and different obstacles.The results show that wind speed affects the direction,distance,concentration and spread balance time of diffusion.The existence of the obstacles changes the conventional diffusion path and makes the concentration accumulation of cavity area.The results will be helpful for safety accident rescue.
