알루미늄 입자가 다량 함유된 고폭약의 데토네이션 특성에 대한 수치적 연구

The problem of non-ideal detonation propagation velocities in heterogeneous hybrid mixtures is studied in the case of a High Explosive with suspended fine aluminum particles. Since there exist difference in the time scales of the characteristic induction and combustion of High Explosives and solid particles, the process of energy release behind the leading shock front occurs over an extended period of time. The problem is analyzed by the theory of the mechanics of multiphase media with mass, momentum and heat exchanges between particles and gases. The numerical results match the available experimental results of Heavily Aluminized (5-25% Al weight) HMX explosive obtained previously.
