Dynamical Model Based on Hydrodynamics for Relativistic Heavy-Ion Collisions

Abstract

We present a state-of-the-art algorithm for solving the relativistic viscous hydrodynamic equation with QCD equation of state. We apply the algorithm to several numerical test problems such as sound wave propagation and shock tube problem. In the sound wave propagation, the intrinsic numerical viscosity is measured and its explicit expression is shown. We apply our numerical algorithm to investigation of higher harmonics in relativistic heavy ion collisions.
