Bulk Viscous Cosmological Models in General Relativity

Abstract

A new class of exact solutions of Einstein's field equations with bulk viscous fluid for an LRS Bianchi type-I spacetime is obtained by using deceleration parameter as variable. The value of Hubble's constant $H_0$ is found to be less than one for non-flat model and is equal to 1.5 for flat model which are of the physical interest. Some physical and geometric properties of the models are also discussed.
