Slow heat-driven flow in a gas of hard disks
Amit Kumar, Abhishek Dhar, Baruch Meerson
We study a slow heat-driven flow in a gas of elastically colliding hard disks confined to a long channel. The initial state consists of two regions with large temperature and densi…
Splash in an inhomogeneous gas in one dimension: Exact analysis and molecular dynamics simulations
Amit Kumar, R. Rajesh
We investigate the splash phenomenon resulting from the energy input at the interface between a vacuum and an inhomogeneous gas with density profile . The energy…
Shock propagation following an intense explosion in an inhomogeneous gas: core scaling and hydrodynamics
Amit Kumar, R. Rajesh
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 varia…
Shock propagation in a driven hard sphere gas: molecular dynamics simulations and hydrodynamics
Amit Kumar, R. Rajesh
The continuous injection of energy in a stationary gas creates a shock wave that propagates radially outwards. We study the hydrodynamics of this disturbance using event driven mol…
