摘要

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, the thermal freeze-out temperature dependence of average radial flow, the spatial size of the fluid are different from the results by using a conventional hydrodynamic model in which chemical equilibrium is always assumed. We also analyse the pt spectrum andⅴ_2(pt) at the RHIC energy and consistently reproduce experimental data by choosing the thermal freeze-out temperature T_(th) = 140 MeV.
