AI Article Synopsis
- The study focuses on the non-equilibrium characteristics that emerge during the process of shock relaxation, especially when two shock waves collide, which differs from a single shock wave's behavior.
- Using non-equilibrium molecular dynamics simulations, researchers assessed how ultra-strong shock waves interact in a classical gas and examined the link between equilibrium relaxation time and the intensity of these shocks.
- The findings highlighted that the movement of microscopic particles during the collision significantly affects energy changes, offering new insights into the microscopic mechanics of the relaxation process.
Article Abstract
The non-equilibrium characteristics during the shock relaxation process hold a foundational position in various fields. In contrast to the propagation of a single shock wave, the collision process of two shock waves exhibits distinct non-equilibrium features. Employing non-equilibrium molecular dynamics, we simulated the collision of ultra-strong shock waves in a classical gas system, investigating the relationship between equilibrium relaxation time and shock intensity. Tracking the spatial migration of microscopic particles in the shock collision region during the relaxation process, we observed a significant contribution of particle migration to the average energy changes during relaxation. The discussion on particle migration provides a valuable new perspective for understanding the microscopic mechanisms of the relaxation process.
