A Statistical Hot Spot Reactive Flow Model for Shock Initiation and Detonation of Solid High Explosives
Phenomenological reactive flow models for the shock initiation and detonation of solid high explosives, such as the Ignition and Growth model and the Johnson-Tang-Forest (JTF) model have been very successful in reproducing most of the main features of these reactive flows. The reaction rate expressions in these models depend upon the average compressions and pressures attained in the reacting e...
متن کاملHigh Order Phase-fitted Discrete Lagrangian Integrators for Orbital Problems
In this work, the benefits of the phase fitting technique are embedded in high order discrete Lagrangian integrators. The proposed methodology creates integrators with zero phase lag in a test Lagrangian in a similar way used in phase fitted numerical methods for ordinary differential equations. Moreover, an efficient method for frequency evaluation is proposed based on the eccentricities of th...

چکیده این پایان نامه به بررسی اثر سیم پیچ مغناطیسی و کاوه یِ خوشه گر با بسامد رادیویی بر هاله و بیرونگراییِ باریکه هایِ پیوسته و خوشه ایِ ذرات باردار در شتابدهنده های خطیِ یونی، پروتونی با جریان بالا می پردازد و راه حل هایی برای بهینه نگهداشتن این کمیتها ارایه می دهد. بیرونگرایی یکی از کمیتهای اساسی باریکه هایِ ذرات باردار در شتابدهنده ها است که تاثیر قابل توجهی بر قیمت، هزینه و کاراییِ هر شتابدهند...
Studies on Empirical Approaches for Estimation of Detonation Velocity of High Explosives
Despite many computer based codes like CHEETAH, TIGER, RUBY, BKW, etc. the velocity of detonation (VOD) for explosive molecules and explosive mixtures (formulations) is estimated by several empirical formulations. This article discusses various approaches for the estimation of the velocity of detonation by empirical mathematical equations. The formulation proposed by Kamlet in 1968 is the oldes...
متن کاملShock-initiation and Detonation Extinction in Homogeneous or Heterogeneous Explosives: Some Experiments and Models
Chemical explosives can be found in the gaseous, liquid or solid phases but it is customary to distinguish homogeneous explosives from heterogeneous ones. Indeed experiments have revealed that the dynamical behaviors of detonative or quasi-detonative decomposition regimes of explosives have more to do with the latter classification than with the former. However, distinguishing between homogeneo...
