Bianchi Type-I Cosmological Model in the Presence of Wet Dark Fluid with Magnetic Flux

Abstract

The object of this paper is to investigate the nature of Bianchi type-I cosmological model in presence of wet dark fluid and magnetic flux. To obtain deterministic solution of said model a few plausible assumptions regarding to it are introduced such as scalar expansion θ is proportional to eigenvalue σ₁¹ of shear tensor σ_jⁱ. A new equation of state for the dark energy component of the universe has been used. It is modelled on the equation of state p = (ρ – ρ_*)  which can describe a liquid, for example water. The exact solutions to the corresponding field equations are obtained in quadrature form. The solution for constant deceleration parameter have been studied in detailed for both power-law and exponential form. In addition to this we have discuss the geometrical and physical properties of said model.
