Tilted Bianchi Type V Bulk Viscous Cosmological Models with Varying Λ-Term
Anirudh Pradhan, S. K. Srivastav
Abstract
Conformally flat tilted Bianchi type V cosmological models in presence of a bulk viscous fluid and heat flow are investigated. The coefficient of bulk viscosity is assumed to be a power function of mass density. The cosmological constant is found to be a decreasing function of time, which is supported by results from recent type Ia supernovae observations. Some physical and geometric aspects of the models are also discussed.
