equation of state, two different models of the universe are obtained. It is
observed that Kantowski-Sachs vacuum model obtained in first case and bulk
viscous fluid model obtained in second case. It is also observed that the bulk
viscous cosmological model always represents an accelerated universe and
consistent with the recent observations of type-1a supernovae. Some physical
and geometrical features of the viscous fluid model are studied.
