چکیده انگلیسی
In case of a vehicle fire, an installed LPG (liquefied petroleum gas) tank with a malfunctioning safety device poses severe hazards. To investigate the consequences in case of tank failure, we conducted 16 tests with toroidal shaped LPG vehicle tanks. Three tanks were used for a Hydraulic Burst Test under standard conditions. Another three tanks were equipped with a statutory safety device and were subjected to a gasoline pool fire. The safety device prevented tank failure, as intended. To generate a statistically valid dataset on tank failure, ten tanks without safety devices were exposed to a gasoline pool fire. Five tanks were filled to a level of 20%; the remaining five were filled to a level of 100%. In order to gain information on the heating process, three temperature readings at the tank surface, and three nearby flame temperatures were recorded. At distances of l = (7; 9; 11) m to the tank, the overpressure of the shock wave induced by the tank failure and the unsteady temperatures were measured. All ten tanks failed within a time of tâ¯<â¯5â¯min in a BLEVE (boiling liquid expanding vapor explosion). Seven of these resulted directly in a catastrophic failure. The other three resulted in partial failure followed by catastrophic failure. A near field overpressure at a distance of lâ¯=â¯7â¯m of up to pâ¯=â¯0.27â¯bar was measured. All ten tests showed massive fragmentation of the tank mantle. In total, 50 fragments were found. These 50 fragments make-up 88.6% of the original tank mass. Each fragment was georeferenced and weighed. Fragment throwing distances of lâ¯>â¯250â¯m occurred. For the tanks with a fill level of 20%, the average number of fragments was twice as high as it was for the tanks that were filled completely.
