  We study the dynamics of first-order cofinement-deconfinement phase
transition through nucleation of hadronic bubbles in an expanding quark gluon
plasma in the context of heavy ion collisions for interacting quark and hadron
gas and by incorporating the effects of curvature energy. We find that the
interactions reduce the delay in the phase transition whereas the curvature
energy has a mixed behavior. In contrast to the case of early Universe phase
transition, here lower values of surface tension increase the supercooling and
slow down the hadronization process. Higher values of bag pressure tend to
speed up the transition. Another interesting feature is the start of the
hadronization process as soon as the QGP is created.
