摘　　要：以某石油化工企业的LPG球罐罐区为研究对象,在对现场实际情况进行简化和抽象的基础上,采用ANSYS FLUENT软件对LPG球罐区的泄漏扩散进行三维数值模拟计算。主要研究了不同风速条件下LPG扩散的变化规律,得出了风速对LPG球罐泄漏扩散的扩散方向、距离以及浓度产生的影响。该研究结果对球罐区的事故预防具有指导意义。Taking some petrochemical enterprise of LPG spherical tank and tank farm as the research object,based on the actual situation to simplify and abstract,using ANSYS FLUENT software for leakage of LPG spherical tank area spread 3- d numerical simulation,the change rule of LPG diffusion at different wind speeds was mainly studied. It was concluded that the wind speed had an effect on the LPG spherical tank leakage diffusion direction,distance,and concentration. The results of the study have guiding significance for the prevention of tank area accident.
