Abstract
Some hypersurface-homogeneous cosmological models with bulk viscous fluid and time-dependent cosmological term are investigated. These expanding, shearing and non-rotating cosmological models of the universe evolve from initial big-bang singularities and give an essentially empty space for large times. Some physical and geometric behaviors of these models are also discussed.
