Molecular Dynamics Analysis of Shock Wave in One Dimensional High Speed Compressed Ar Gas

In conventional fluid mechanics, fluids are described as continuum. On the atomic scale, fluids are discrete. Shock waves are an important phenomenon in various fields such as high-speed fluid mechanics, explosions, and space engineering. Understanding their behavior will lead to many technological innovations. In conventional simulation technology, atomic scale information is limited. In present simulation study by molecular dynamics (MD) using LJ potentials, Ar gas is fast compressed in one dimensionally. After the compression, spatial inhomogeneities, such as pressure, are analyzed in the atomic or voxel level. we gain insight into shock wave and compressed gas on the nanoscale order.
