油箱明火烤燃燃爆特性实验研究
Experimental study of cook-off performance of fuel tanks
摘要
Abstract
Vehicles are apt to catch fire easily in high temperature weather or in traffic accidents.When their fuel tanks cook off,an explosion may occur,thereby posing a hazard to personal safety.To investigate the cook-off performance of fuel tanks,we conducted 4 tests on 76 L fuel tanks under different airtight conditions and infillings,and obtained the surface and internal temperatures and the size of the fireballs using an infrared thermal imager,thermocouples and a camera.The experimental results show that the explosion may occur when the fuel outlets are closed and the fuel tank is not filled with explosion suppression balls.In our experiments,the highest surface temperature of the explosion fireball was above 1 800 K,and the volume of the fireball was 1 600 times more than that of the fuel tank.The explosion suppression balls filled in the tanks decreased the highest surface temperature and sizes of the jet fire.Under the same conditions,the average heating rate and the highest temperature of the diesel fuel vapor were 36.0% and 16.2% lower than that of the gasoline vapor respectively.关键词
