Abstract:

In present paper we have investigated the inflationary scenario in Bianchi Type V cosmological model under the effect of bulk viscosity in general relativity. To get deterministic model of the universe, we assume the shear (sigma) is proportional to the expansion (theta) by which a condition A1 = (A2A3)n between metric potentials is obtained. We consider the region is flat which leads to the scalar potential V(phi) is constant. We found the spatial volume increases with time, which represent the inflationary scenario in the model. Some physical and geometrical properties of the model are also discussed in detail. The model is found to be compatible with the results of recent observations.
