Reconstruction Of New Agegraphic Chaplygin Gas Model With Viscosity

Astronomical observations in recent years show that:the current universe is not only ex-panding, but also is experiencing an accelerated expansion. It is an opening object that what is driving the accelerating expansion of universe. At present many theories have put forward, and the cosmological constant called vacuum energy is considered as the best candidate of dark energy. A variety of dark energy models have been established, but all of them have their own advantages and disadvantages.In this paper we briefly study the viscous effects on the reconstruction of the new Age-graphic (NADE) and the Chaplygin gas (MCG) models. First, we research the evolutions of ωq for three different interacting new Agegraphic with viscosity. The results show that when the interaction terms are Q1=3Hb2ρq and Q2=3Hb2ρdm, the ωq can cross the phantom divide. The viscosity delays the crossing of phantom divide, and the bigger the viscosity is, the later crossing of phantom divide is.Next, this paper discuss the interacting MCG model in non-flat universe considering the NADE as dark energy. We reconstruct the potential V(Φ) and the scalar field Φ(a), and study the evolutions for the different interacting strengthes respectively.Finally, on the basis of the above results, we consider the effects of viscosity. In particular, we reconstruct the potential V(Φ) and the scalar field Φ(a) for the different strength interactions, and analyze the viscous influence on the evolutions of V(Φ) and Φ(a).
