摘要
当油气管线或是储油罐发生小口径的破裂时,就会发生油气扩散,当扩散的油气经过场区居民区等楼体障碍物时,会给人们生命安全带来一定的影响。ANSYS软件基于研究场区障碍物对油气扩散的绕流影响,模拟得到不同速度、压强的分布范围图,为初步判断油气扩散的浓度范围提供了一定的方法和依据,为场区的安全疏散提供一定的参考价值。
Oil and gas diffusion occurs when small-caliber rupture appears on oil and gas pipelines or oil tanks. Diffused oil and gas will affect the safety and even life of the residents when passing through building obstacles in plants and residential areas. Based on the obstacles in the research region, ANSYS software can simulate the circumfluence of the diffused oil and gas and draw the distri- bution chart of different speed and pressure, so as to provide approaches and basis for the primary judgment of the concentration range of oil and gas diffusion and offer reference for the safe escape in plants and residential regions.
