Characteristic Analysis of Shock Wave for Underwater Explosion of Aluminized Explosive

Using the one-dimensional hydrodynamics code and the time-dependent JWL EOS, using a pressure exponent of 1/6 in the pressure-dependent rate law, this paper calculates the relationships between characteristic parameters of shock wave and reaction rate for underwater explosion of aluminized explosive. The results show that there is a critical value in the rate constants,and that the blasting energy can be used efficiently only if the rate constant is larger than the critical value. In the view of the relationships between aluminum size and the constant, we can design different energy output characteristics through dominating aluminum size.
