[ 1 ] - مروری بر روش های عددی شبیه سازی موج بلست انفجار

As the computation power developing, the simulation of the explosion blast wave becomes more accurate and much more codes and softwares designed for this purpose. Besides the numerical methods, there are some other effectives like: turbulence model, equation of state and the explosion models which affect the accuracy of the blast wave simulation results. This paper reviewed the numerical method...

[ 2 ] - استخراج ضرایب نرخ سوزش پیشرانه تفنگی بر اساس داده های تست محفظه بسته

When dealing with research and development of gun propellants, a less expensive, quicker and safer process of closed vessel evaluation adopted rather than gun firing. In the current research work a computer program (BRCBADR) has been developed for the burning rate reduction from closed vessel test data. Correct determination of thermo-chemical properties of propellants provides accurate results...

[ 3 ] - تحلیل عددی بالستیک داخلی سلاح برای پیشرانه های تفنگی با لایه تاخیری

In the current research work, a zero-dimensional code for the internal ballistic weapon analysis has been developed with a deterrent layer propellant. Today, the driving of the deterrent layer is widely used in small and medium-caliber weapons. The deterrent layer is in the form of a thin coating on the surface of a single base or double  base gun propellants. The main purpose of this type of s...

[ 4 ] - استخراج پارامترهای نرخ واکنش آغازش و رشد (I&G) برای ماده منفجره Comp-B

One of the most important issues when working with energetic materials is their initiation. Of the various methods of energetic materials initiation in the military and civilian industries, shock initiation is of particular importance. Numerical and simulation study of the shock initiation of condensed phase explosives is related to models called burning rate models, which describe the conversi...
