[ 1 ] - Molecular Dynamics Simulation of Al/NiO Thermite Reaction Using Reactive Force Field (ReaxFF)
In this work, the thermal reaction of aluminum (Al) and nickel oxide (NiO) was investigated by molecular dynamics simulations. Some effective features of reaction such as reaction temperature, the reaction mechanism, and diffusion rate of oxygen into aluminum structure were studied. ReaxFF force field was performed to study the Al/NiO thermite reaction behavior at five different temperatures (5...
[ 2 ] - تجمع الکتریسیته ساکن در سوخت های مایع، اندازه گیری و کنترل آن
Abstract Liquid fuels usually have low electrical conductivity leads to accumulating in static electricity during transmission, mixing and spraying processes. This charge accumulation will spark and fire if it exceeds the air ionization energy. Therefore, one of the important parameters in fuels safety is their potential for static charge accumulation. In this manuscript, materials are classif...
[ 3 ] - کاهش بار ساکن در ترکیبات انفجاری HMXو PETN با استفاده از پارافین و افزودنی‌های رسانا
HMX and PETN explosives are the most important and usable explosives in the military and defense industries and possess wide range of applications for military as well as commercial applications. Numerous difficulties are encountered during the processing, conveying and storage of powders which are all attributed to their electrostatic charging. Indeed, charged powders could cause damage rangin...
[ 4 ] - بهبود قطبیت واکس پارافین از روش پیوند زنی رادیکال آزاد مالئیک انیدرید و ارزیابی عملکرد آن به کمک حلال‌های دیپ اتکتیک
Being non-polar and considerably high electrical resistivity are significant drawbacks of the crystalline paraffin wax used for desensitizing energetic materials. Here, as a practical approach to improve the wax properties, maleic-anhydride was reacted with paraffin wax in the presence of a free-radical initiator. Then, the reaction success was approved by employing Attenuated Total Reflection-...
[ 5 ] - مروری بر مکانیزمهای تشکیل نقاط داغ در آغازگری مواد پرانرژی
The Study of Hot Spots as a Cause of Circumstantial Initiation in Energetic Materials in order to Increase Work and Storage Safety of these Materials is of Special Importance. Hot Spots, by Converting Different Types of Force like Mechanical Forces, Friction, Heat, and… into Heat, Cause the Temperature to Rise Exponentially by about 700 Kelvin in 10-3 to 10-5 Seconds at that Point. If This Temp...
