摘要：

In this paper, we consider the generalized anisotropic model in Einstein's theory of gravity to study evolution of anisotropic universe. For this purpose, we consider interacting form of dark energy model and evaluate some exact solutions corresponding to Bianchi type-III, V and VI models. We study the behavior of these solutions through some standard cosmological parameters such as Hubble, squared speed of sound, equation of state and state-finder parameters. We also discuss the evolution of fractional energy densities of ordinary matter and dark energy. The graphical behavior of these parameters against red-shift parameter provides consistency with current observations.
