Thermal Stimuli

Thermal stimuli is one of the major external stiumuli resulting from an overheated explosion of a munition. In order to evaluate the influence of external thermal stiumuli on the thermal hazards of JEOL-1 (32 wt% octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX), 32 wt% 3-nitro-1,2,4-triazole-5-one (NTO), 28 wt% Al and 8 wt% binder system) explosive, accelerating rate calorimeter (ARC) is used to study the adiabatic thermal decomposition properties of JEOL-1 molding powders, and the slow cook-off properties of JEOL-1 are studied by experimental test and numerical simulation. The activation energy Ea, pre-exponential factor A, mechanism function f(α) and self-accelerating decomposition temperature (SADT) of adiabatic thermal decomposition of JEOL-1 molding powders are obtained according to ARC results. The response level of JEOL-1 polymer bonded explosive (PBX) columns exposed to an engulfing liquid pool fire is examined by the slow cook-off test. The ignition location, ignition temperature, ignition time and the transient temperature distributions of JEOL-1 PBX columns during the slow cook-off are obtained by numerical simulation. It can be concluded from this study that JEOL-1 is a low vulnerable explosive with high thermal safety.

Atomization Nozzle

The atomization process of liquid droplet is an important stage in the fluid movement process in the jet exhausting atomization nozzle. This stage is directly influenced on the diameter and desperation of water droplet. Today two-dimensional model is often used in the most common simulation framework. But the atomization process in nozzle is usually happened in the three-dimensional model, so the results are not quite agreed with the practice. In this paper, a new three-dimensional model was proposed to study the mechanism of the atomization process. After applying the VOF method and turbulent model in CFD software Fluent, a numerical simulation was performed to analyze the mechanism of atomization process and some related factors affecting the atomization. Results indicated that the shapes of atomization were accorded with experimental investigations. According to the results, the necessity of further characteristic parameters on the atomization process was analyzed.
