Numerical Simulation of TNT-Al Explosives in Explosion Chamber
نویسندگان
چکیده
The Numerical modeling of burning particles, initiated from a heavily aluminized High Explosive (HE) is being investigated. Reactive multiphase flows must be modeled to properly account for variable-size aluminum particles burning behind the blast wave. The governing equations also include models for solid evaporation and chemical reactions. The final paper will present comparison of experimental data and computational results of mixed TNT-Al detonation and burning in a closed chamber.

شبیه سازی آزمون ایمپالس متری VLIP و ارائه روشی برای تعیین معادل TNT انفجاری
The VLIP is a usefull system to compare the high explosives efficiency. This device includes a metallic plate which located above the explosive material and upthrown vertically due to the explosion. The exerted impulse on the plate is used as a meter to determine the explosives efficiency. Since the VLIP system has a low cost, in this paper a method based on VLIP is presented to determine the T...

Based on the double shockwave approximation procedure and combining the real ghost fluid method (RGFM) with the level-set method, a local Riemann problem for strongly nonlinear equations of state such as the JWL equation of state is constructed, which has suppressed successfully the numerical oscillation caused by high-density ratio and high-pressure ratio across the interface between the explo...

In this article charging of explosives through casting has been investigated. Melt casting of TNT-based explosives is one of the most common techniques to economic and mass production of explosives. TNT is the only molten explosive at low temperature (80.4 C), so it is a convenient matrix for casting. Shrinkage of TNT in amount of 11-12% during solidification causes some problems in melt cast...

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...

This study describes the biological degradation of TNT by using induced aeration. Three plastic reactors were used. In each reactor 3 kg of soil were used. In order to increase the porosity of the soil, sawdust was added to soil. Textile wastewater treatment plant sludge was also added to soil. TNT at the concentrations of 1000 mg/kg of soil was added thereafter. Rhamnolipid biosurfactant at th...
