    Opis:
    This work focuses on the development of models for predicting explosive power and air blast from the detonation of organic peroxides (TATP and HMTD) and non-ideal explosives involving ammonium nitrate, urea nitrate, and chlorates. CHEETAH calculations assuming ideal behaviour are in agreement with literature data for peroxides. However, the detonation behaviour of non-ideal explosives is dependent on charge size and confnement. This behaviour is investigated using thermo-chemical calculations with Kinetic CHEETAH, and reactive fow models with AUTODYN. A simplifed ignition and growth (I&G) model was calibrated using experimental charge diameter vs. VoD data. I&G models are used to predict the front curvature, reaction zone structure, and energy release from the non-ideal explosives. Detonation and air blast predictions for peroxides and unconfned and confned (paper, plastic, steel) non-ideal charges are presented.

    Opis:
    The heat of explosion is one of the most important thermodynamic parameters of aluminized explosives. Two improvements in numerical calculations to predict the behaviour of the explosion of non-ideal aluminized explosives were completed in this work. The chemical reaction between aluminum and the C-J detonation products of high energy ingredients was determined and the equation of state for the detonation products of high energy ingredients was revised. The constant k in the BKW equation was revised to obtain perfect results for predicting the C-J parameters for high energy ingredients. The predicted results show that the heats and temperatures of aluminized explosives become maximized when the mass fraction of aluminum powder is 30%, which is in good agreement with the results obtained by empirical formulae.

    Opis:
    A general and simple method has been developed for calculating the detonation pressure of different kinds of ideal and non-ideal explosives containing aluminum (Al) and ammonium nitrate (AN). The new model can be applied to CHNO and CHNOFCl explosives in pure form or as mixtures as well as non-ideal mixed explosives including Al and AN. It can also be used for different plastic bonded explosives (PBXs). There is no need for any prior knowledge about the measured or calculated properties of the explosive. The only data needed are the standard enthalpy of formation and the loading density of the desired explosive. The predicted detonation pressures were compared with other predictive methods and outputs of BKWS-EOS, in both full and partial equilibrium. Different statistical parameters as well as cross validation parameters showed that the new model is precise, accurate, well-defined, and robust for predicting the detonation pressures of CHNOFCl(Al/AN) energetic materials.

    Opis:
    An improved simple method is presented for calculation of the detonation velocity of CHNO and CHNOFCl explosives, as well as non-ideal explosives containing aluminum (Al) and ammonium nitrate (AN) additives. In contrast to the available complex computer codes, where the estimated detonation velocities of non-ideal explosives for equilibrium and steady state calculations show significant differences from the measured data, this simple method gives more reliable results. Suitable decomposition paths are suggested in which the partial interaction of Al with the gaseous products and the decomposition of AN are assumed for composite explosives containing Al/AN additives. The predicted detonation velocities using the new method are good compared to those from one of the well-known empirical methods and from computer codes using full and partial equilibrium of Al/AN.

    Opis:
    ANFO is a well-known, reliable and safe commercial explosive. It has been around since the late 1950’s and its detonation properties are well characterized. In this study, the detonation process of dry, wet and aluminised ANFO, was recorded using two high-speed cameras with recording rates of 1,200 fps and 50,000 fps. The 1,200-fps footage allowed the observation of the post blast fumes (i.e. NOx) produced by ANFOs with different water contents. The 50,000-fps footage allowed the observation of the detonation area, gas expansion phase and the measurement of the velocity of detonation (VOD). The video footage also recorded a bright zone in front of the gases (longer than 50 mm). We assumed that a reaction is taking place in this zone, but it is difficult to be sure if this is the reaction zone or not as it is longer than previously reported reaction zone lengths. Analysis showed that ANFO detonates effectively for water contents of up to 9 wt.%, and more importantly, there is little variation in the VOD. As far as the expansion of gases is concerned, the ANFO-Al expansion rate appears to be different. In this mixture, the absence of NOx fumes could have been due to the expected higher temperatures produced by the burning of the aluminium additive as observed in the images recorded with the high-speed camera.
