强爆炸引起的粒子弥散
Dispersion of particles by a strong explosion
摘要：
在局部高能异常（爆炸）影响下的粒子输运动力学是一种复杂的现象，取决于粒子及其所在介质的许多物理参数。在这里，我们提出了一个概念模型，建立简单的比例律颗粒分散在爆炸中释放的能量，介质的性质，颗粒的物理性质和它们的初始位置远离爆炸震中。这些依赖关系的数值模拟验证，我们讨论的模型，可以通过实验验证的预测。其他应用程序和扩展的框架也被认为是。
英文摘要：
The dynamics of particle transport under the influence of localised high energy anomalies (explosions) is a complicated phenomena dependent on many physical parameters of both the particle and the medium it resides in. Here we present a conceptual model that establishes simple scaling laws for particle dispersion in relation to the energy released in a blast, properties of the medium, physical properties of particles and their initial position away from a blast epicenter. These dependencies are validated against numerical simulations and we discuss predictions of the model which can be validated experimentally. Other applications and extensions to the framework are also considered.
