On an exact hydrodynamic solution for the elliptic flow

Abstract: (arXiv)
Looking for the underlying hydrodynamic mechanisms determining the elliptic flow we show that for an expanding relativistic perfect fluid the transverse flow may derive from a solvable hydrodynamic potential, if the entropy is transversally conserved and the corresponding expansion 'quasi-stationary', that is mainly governed by the temperature cooling. Exact solutions for the velocity flow coefficients and the temperature dependence of the spatial and momentum anisotropy are obtained and shown to be in agreement with the elliptic flow features of heavy-ion collisions.- 24.10.Nz
