Hydrodynamical Expansion of Viscous QGP Fluid with Phase Transition
Department of Physics, Waseda University, Tokyo 169
(Received May 11, 1989)
Hydrodynamical expansion of a viscous fluid with phase transiton is numerically simulated
within the thoretical framework of a semiphenomenological transport theory of the quark-gluon
plasma with and without Bjorken's ansatz. Finally we find that the lifetime of the quark-gluon
plasma becomes remarkably longer by virtue of the effect of phase transition and dissipation, and that
Reynolds number grows up with fluid cooling. We also show that the scaling solution can effectively
work even when viscosity and phase transition exist.

This paper also discuss viscous fluid with phase transition, but it seems that our method more systematically parametrizes thermodynamical quantity and viscosity with common parameters.
