Abstract

Abstract

In order to simulate the scene of secondary explosion caused by the fuel tank of vehicle, equipment bombarded, the shelling experiments of Ø30 mm fragmentation explosive incendiary shell were conducted in the external field. The process of diesel fuel detonated and temperature parameters of fireball were recorded by a high-speed camera, the infrared thermal imager separately. Explosion performance of ordinary diesel fuel, diesel fuel with water content and explosion suppression diesel fuel were compared and evaluated. The results show that the explosion fireball occurs due to the explosive energy acting on aerosols which result from quick mixing of air and diesel fuel dispersed from the fuel tank at the moment when shells shoot the fuel tank. The development all the explosion fireballs have three phases, but there are still notable differences in the sizes, expanding rates and surface temperatures among explosion fireballs of three types of diesel fuel. These three fireball parameters of ordinary diesel fuel and diesel fuel with water content are similar, which are greater than that of explosion suppression diesel fuel. Fuel tank damage volume of diesel fuel with water content is 108.00 dm³, which is far greater than that of ordinary diesel fuel (57.65 dm³) and explosion suppression diesel fuel (38.15 dm³). The results also confirm the difference between three types of diesel fuel in explosion performance.
