N2  - In order to analyze evolution of accident chain of "leakage-burning-heat feedback-temperature/ pressure increase-stronger leakage", which is triggered by ignition of fuel leaked from LNG tanker, a coupling model of leakage-burning was developed based on typical situation in China. And effects of leakage phase, filling ratio and aperture on leakage accident development were analyzed. The results show that pressure in tanker might increase sharply and explode caused by positive feedback between leakage rate and burning heat flow at the leakage stage of liquid. It would be more dangerous in early leakage stage for low filling ratios while peak pressure would be higher for high filling ratios. The peak pressure of tanks normally decreases along with increase of aperture within certain range and at certain filling ratios. © 2019 China Safety Science Journal<p /> <p>Language: zh</p>
