摘要
Abstract
In this research,to investigate the pressure distribution of the shaped charge explosive in the underwater near-field,we conducted both experimental studies and numerical simulation and,by comparing the results from the simulation with those from the experiments,validated both the numerical model and the computation.We used the numerical method to investigate the distribution and propagation of the shockwave and the energy in underwater explosion by the shaped charge.The results show that the distribution of the shockwave in the near field is non-uniform and the isopiestic is irregular;the pressure disturbance of the water in front of the shaped charge penetrator is significant,which enhances the positive blast wave;and the evolution of the wave front in the near field is pear-shaped.关键词
