主 题:Aluminum-based fuel Heterogeneous nucleation Molecular dynamics simulation Thermal reaction High energy laser-induced shockwave experiment
摘 要:To improve the thermal properties of aluminum(Al)in the energetic system,a coated structure with ammonium perchlorate(AP)was prepared by a facile *** N,N-Dimethylformamide(DMF)was chosen as an ideal solvent based on heterogeneous nucleation theory and molecular dynamics *** coated structure could enlarge the contact area and improve the reaction environment to enhance the thermal *** addition of AP could accelerate oxidation temperature of Al with around 17.5°*** the heat release of 85@15 composition rises to 26.13 k J/g and the reaction degree is97.6%with higher peak pressure(254.6 k Pa)and rise rate(1.397 MPa/s).An ideal ratio with 15 wt%AP was probed *** high energy laser-induced shockwave experiment was utilized to simulate the reaction behavior in hot *** the larger activated mixture of coated powder could release more energy to promote the growth of shockwave with higher speed up to 518.7±55.9 m/*** conclusion,85@15 composition is expected to be applied in energetic system as a novel metal fuel.
