基于PHAST软件的港口常压储罐多米诺效应研究
Study on domino effect of port atmospheric storage tank based on PHAST software
摘要
Abstract
There are many atmospheric storage tanks in the dangerous goods storage area of the port,and the domino effect caused by the accident will cause heavy losses.Based on the PHAST software,the secondary effects of leakage,fire and explosion accidents and the domino effect development law of the gasoline tank group near the dangerous goods loading and unloading berth in a coastal port of China were studied.The results show that there are many influencing factors for the domino effect,among which the change in leakage aperture has a significant impact on the domino effect of pool fire accidents,vapor cloud explosion accidents,and jet fire accidents.When the leakage aperture is small,the thermal radiation changes in pool fire accidents are more severe,resulting in a shorter time for the domino effect to occur;however,when the leakage aperture is slightly larger,the combustion of the gasoline pool is relatively stable,which can prolong the time for the domino effect to occur.As the leakage aperture increases,the farthest impact distance that may cause the domino effect in vapor cloud explosion accidents shows a significant increasing trend.A jet fire accident may only cause a domino accident when it occurs on the side near the surrounding storage tank,and the relationship between the flame length and the leakage time is relatively weak,mainly influenced by the size of the leakage aperture.关键词
