Abstract

We have investigated Bianchi type I bulk viscous barotropic fluid cosmological model with varying Λ and functional relation on Hubble parameter in self-creation theory of gravitation. It is observed that the scalar function ϕ(t) affected the physical parameters of the universe and our model may have more than three spatial-dimensions in the beginning which is a theoretical evidence pointed out in the geometry of universe. The propose variation law for Hubble parameter leads cosmological model which is dominated by decelerating phase at initial stage and at later stage, the universe has accelerating phase and the universe expanding exponentially with acceleration supporting the observational data. Also other geometrical and physical properties of the model have been evaluated.
