Bianchi Type-IX viscous fluid cosmological model is investigated. To get a deterministic model, we have assumed the conditiona = b^m(m is a constant) between metric potentials andη ∞θ whereη is the coefficient of shear viscosity andθ the scalar of expansion in the model. The coefficient of bulk viscosity (ς) is taken as constant. The physical and geometrical aspects of the model are also discussed.

In this paper, we have studied spatially homogeneous anisotropic Bianchi type-I viscous fluid dark energy cosmological model interacting in the framework of scalar tensor theory (Saez–Ballester, Phys. Lett. A 113, 467 (1986)). The field equations are solved by applying a special variation law (power law) for the generalised Hubble parameter. It is observed that the present accelerated expansion of the Universe is affected by the distribution of dark energy. Some physical and geometrical features of the model have also been discussed.
