[ 1 ] - تحلیل دینامیک سیالات محاسباتی موج انفجار با لحاظ نمودن موانع هندسی در محیط انفجار

In this research, three dimensional transient simulations of explosion shockwaves have been performed by using computational fluid dynamics (CFD). For this purpose, the characteristics of explosive mass and the geometry of explosion environment have been imported to Ansys Fluent CFD software. The simulation results have been validated by using experimental data obtained from literature. The com...

[ 2 ] - اثر افزودنی‌های کاهش‌دهنده ویسکوزیته بر فرآیند پذیری مواد منفجره پلیمری

The purpose of this paper is to review the effect of polymer additives on the final viscosity of PBX slurry and viscosity reduction mechanism. Variables related to the formulation and manufacturing process affects PBX viscosity. PBX viscosity directly affects the process of mixing and charging of these materials and hence it is necessary that the viscosity values to be low in order to facilitat...

[ 3 ] - بررسی رفتار حرارتی آمونیوم پرکلرات میکرونیزه تولید ‌شده با روش تبلور ضد‌ حلال بهبود ‌یافته

Ammonium perchlorate (AP) is considered as a strong oxidizer in solid propellants. Therefore, its thermal decomposition characteristics directly influence the combustion behavior of solid propellants. The AP particle size, shape, and morphology influence on the thermal behavior. In this study, the solvent anti-solvent crystallization method equipped with an eductor mixer was used as a system fo...

[ 4 ] - مروری بر روش‌های تولید آمونیوم پرکلرات فوق ریز

Preparation of micron and nano sized ammonium perchlorate (AP) particles in propellant formulation is required for access high burning rate propellants. The decomposition and burning rate of AP particles are mainly affected by decreasing the particle size, which can decrease the decomposition temperature, and increase burning rate.  AP particles at the micro and nano-scales, have a great influe...
