This study presents a generalization of the Landau hydrodynamic solution for multiparticle production applied to non-central relativistic heavy-ion collisions. The obtained results show the longitudinal scaling of elliptic flow, v
2, as a function of rapidity shifted by beam rapidity (y − y
beam
) for different energies (
and 200 GeV) and for different systems (Au-Au and Cu-Cu). It is argued that the elliptic flow and its longitudinal scaling are due to the initial transverse energy density distribution and initial longitudinal thickness effect.
