Casualty analysis of major terrorist attacks in recent decades shows an enormous increase
in fatalities and economic losses. Due to frequent terrorist attacks and failure of engineering …

A gas composed of a large number of atoms evolving according to Newtonian dynamics is
often described by continuum hydrodynamics. Proving this rigorously is an outstanding open …

We study the response of an infinite system of point particles on the line initially at rest to the
instantaneous release of energy in a localized region. The blast generates shock waves …

The continuous injection of energy at a localized region in space in a stationary gas creates
a shock wave that propagates radially outwards. We study the hydrodynamics of this …

The self-similar expansion of a blast wave, well-studied in air, has peculiar counterparts in
dense and dissipative media such as granular gases. Recent results have shown that, while …

We study the shock propagation in a spatially inhomogeneous gas following an intense
explosion. We generalize the exact solution of the Euler equation for the spatio-temporal …

We study shock propagation in a system of initially stationary hard spheres that is driven by
a continuous injection of particles at the origin. The disturbance created by the injection of …

The solution for the radial distribution of pressure, density, temperature and flow velocity
fields in a blast wave propagating through a medium at rest, following an intense explosion …

The low value of the speed of sound in dilute granular media permits the study of the
properties of supersonic flows for a wide range of Mach numbers. In this paper, we report the …

We study the radial distribution of pressure, density, temperature and flow velocity fields at
different times in a two dimensional hard sphere gas that is initially at rest and disturbed by …
