Numerical Simulation on the Explosion Effects in a Hangar Deck

SONG Wei-dong1,WU Kai-teng2,NING Jian-guo1(1.State Key Laboratory of Explosion Science and Technology,Beijing Institute of Technology,Beijing 100081,China;2.Department of Mathematics,Neijiang Normal College,Neijiang 641112,Sichuan,China)  
A 3D numerical model for a hangar deck was established by using MMIC3D.Numerical simulation on the flow field distribution was performed by adopting Youngs interface technology under the condition that the explosion happens after the warhead penetrates into the hangar deck.The shock wave distribution in the hangar deck was analyzed by employing Visc3D.Based on experimental results,the pressure curves of different key points and some regularity results were given.The propagation process of shock waves was clearly observed by cartoon processing after the explosion in the hangar deck.All of these results were consistent with the physical phenomenon and the theoretical analysis,which is useful for understanding the physical process and explosion effects of the near field and the far field in the hangar deck.These results present valuable information for the efficient damage to the planes,crew and corresponding facilities in the hangar deck.
