Temperature response of aluminum particle heated by thermal effects of explosive detonation

A analysing system of high speed movement is used to record detonation products expansion process of Nitromethane (NM). The temperature response of aluminum particles is calculated by using thermal penetration theory under thermal effects of NM detonation. The results show that the thermal effect of NM detonation on aluminum particles is more intensive in expansion phase than that in region of NM detonation,whereas this effect on aluminum particles in detonation zone is neglected. Smaller aluminum particle in NM detonation region can be heated to its ignition temperature promptly, impling that aluminum oxidation reaction becomes possible in region of NM detonation.
