Description
We investigate the effect of early chemical freeze-out on radial and elliptic flow by using a fully three dimensional hydrodynamic model. We find that the time evolution of temperature and the thermal freeze-out temperature dependence of average radial flow are different from the results by using a conventional hydrodynamic model in which chemical equilibrium is always assumed. We also analyse the pt spectrum and v2(pt) at the RHIC energy and consistently reproduce experimental data by choosing the thermal freeze-out temperature Tth=140 MeV. (orig.)
