摘要：
We study the evolution of the dark energy parameter within the scope of a spatially non-flat and isotropic Friedmann-Robertson-Walker model filled with barotropic fluid and bulk viscous stresses.We have obtained cosmological solutions that do not have a Big Rip singularity,and concluded that in both non-interacting and interacting cases the non-flat open Universe crosses the phantom region.We find that during the evolution of the Universe,the equation of state for dark energy ωD changes from ωDeff>-1 to ωDeff<-1,which is consistent with recent observations.
