Numerical simulation of ultra-relativistic, heavy-ion collisions

摘要

The collision of two ultra-relativistic, heavy-ions is simulated by solving the time dependent relativistic hydrodynamics equations on an Eulerian grid. A high resolution second order upwind scheme based on the Harten Lax Van Leer (HLLE) method is used in the calculations. We have extended this method for simulating ultra-relativistic, heavy-ion collisions. This strategy is shown to be faster and/or more accurate than other published methods for the simulation of ultra-relativistic heavy-ion collisions.
