Review of Multiscale Modeling of Detonation
Issues associated with modeling the multiscale nature of detonation are reviewed, and potential applications to detonation-driven propulsion systems are discussed. It is suggested that a failure of most existing computations to simultaneously capture the intrinsic microscales of the underlying continuum model along with engineering macroscales could in part explain existing discrepancies betwee...
متن کاملبررسی اثر نسبت NCO/OH بر خواص مکانیکی ماده منفجره پلاستیکی PBXN-109(علمی-پژوهشی)
The aim of this research is improvement of elongation at break of PBXN-109 polymer bonded explosive. Due to the great effect of isocyanate/hydroxyl ratio (r=NCO/OH) on mechanical properties of plastic bonded explosives, in this research, the samples of PBXN-109 with different r-values of 1, 0.95, 0.85, 0.75 and 0.65 were prepared and analyzed by hardness and tensile tests. The results show that...
متن کاملسنتز و فرمولاسیون سیستم بایندر- نرم‌کننده NHTPB-NPB و بررسی خواص عملکردی آن در PBXN-109 اصلاح شده
In this work, nitration of low molecular weight polybutadiene (PB) by a convenient and inexpensive procedure has been investigated. The product (Nitropolybutadiene (NPB) energetic plasticizer) was characterized by FT-IR, 1H-NMR, GPC, TGA, DSC etc. Then NPB energetic polymer plasticizer and nitro-hydroxyl terminated polybutadiene (NHTPB) binder have been replaced with dioctyladiphate (DOA) inert...

متن کاملمطالعه عددی تاثیر موانع مختلف بر پیشگیری از انفجار سمپاتیک در ماده منفجره Comp-B
In this paper, the sympathetic detonation is studied. In this type of detonation, the shock wave of an explosive by passing through a neutral environment (gap) induces the detonation in the second explosive. The study of this phenomenon is important to the safety of the ammunition depot and their transportation. In the present study, the sympathetic detonation in Comp-B has been studied. In thi...
