Non-ideal Detonation Behavior Of Aluminum-containing Explosives

The main works of this paper about aluminized explosives are as follows:1. The diameter effect of aluminized explosivesThe samples of aluminized explosives were selected. We tested the detonation velocity and detonation pressure of different diameters samples, and we also acquired the shape of the detonation front. Basing on the W-K theory, we calculated the size of the chemical reaction zone by using the shape of detonation front. According to the method of DSD, we used analytical method to acquire the steady state developed equation of detonation wave.2. The detonation pressure, reaction zone and released energy of the aluminized explosivesThe detonation pressure of aluminized explosives was calculated according to the PMMA experiment. We analyzed the feasibility of calculating chemical reaction zone by the PMMA experiment. Then we analyzed and compared the process of energy released according to the transmitted process of shock wave under theeffect of the detonation products. We putted forward the energy index Ea toassess the work capability of the aluminized explosives and give the reference for the design of the aluminized explosives.3. Numerically simulating the detonation performance and work capability of the aluminized explosivesWe calculated the detonation performance of the tested explosives and aluminized explosives not contained oxidizer by using thermodynamics codes VLWR. Associated the three dimension non-linearity finite element hydrokinetics codes ANSYS/LS-DYNA, we numerically stimulated the PMMA experiments. We ascertained the reaction rate function parameters according to the results of PMMA experiments. Compared the results between experiment and calculation, we checked up the calculated model and related parameters.
