Numerical Simulation of Thermobaric Explosive Explosion in Free Field

Article Preview

Abstract:

In order to analyze the explosion characteristics on the free field performance of thermobaric explosive, parameters of blast waves produced by the investigated charges in an open space were measured by the use of piezoelectric sensors and the results were compared to traditional TNT. Moreover, a numerical simulation of TBE explosion in free field was performed within the frame of AUTODYN. Comparison with TNT reveals that the values of peak pressure and impulse of TBE are higher than that of TNT due to the secondary reaction of Al and detonation products. It is found that the simulation results of TBE detonation blast wave parameters coincided very well with the experiment data. This demonstrates that the simulation method used is an effective way to depict the spreading of detonation waves in free field for TBE.
