摘　　要：We present various predictions for the anisotropic collective flow of particles in heavy-ion collisions, in particular scaling laws of the second and fourth harmonics v_2 and v_4,derived within ideal fluid dynamics. We also discuss qualitatively the deviation from the ideal behaviour expected in an out-of-equilibrium scenario.We present various predictions for the anisotropic collective flow of particles in heavy-ion collisions in particular scaling laws of the second and fourth harmonics v2 and v4, derived within ideal fluid dynamics We also discuss qualitatively the deviation from the ideal behaviour expected in an out-of-equilibrium scenario
