Abstract :
In this article, we have studied the Bianchi-type V cosmological models which are spatially homogeneous and anisotropic in presence of bulk viscous fluid coupled with one-dimensional cosmic string having the constant deceleration parameter. We have obtained the exact solutions of highly non-linear field equations considering linear gravity, the equation of state, and the spatial law of variation for Hubble’s parameter. Some physical and kinematical properties of the constructed models have been discussed and presented graphically and it is interesting to note that the resultant models are in good agreement with recent observations.
