Interacting Two-Fluid Viscous Dark Energy Models In Non-Flat Universe

We study the evolution of the dark energy parameter within the scope of a spatially non-flat and isotropic Friedmann-Robertson-Walker (FRW) model filled with barotropic fluid and bulk viscous stresses. We have obtained cosmological solutions which exhibit without a big rip singularity. It is concluded that in both non-interacting and interacting cases non-flat open universe crosses the phantom region. We find that during the evolution of the universe, the equation of state (EoS) for dark energy $\omega_{D}$ changes from $\omega^{eff}_{D} < -1$ to $\omega^{eff}_{D} > -1$, which is consistent with recent observations.
