Bianchi Type V Universe With Wet Dark Fluid In Scalar-Tensor Theory of Gravitation

Using Bianchi type V space-time, field equations in presence of wet dark fluid in Saez-ballaster theory are obtained. A new equation of state for the dark energy component of the universe has been used, which is modeled on the equation of state p= ? (?-?*) that can describe a liquid such as water. The exact solutions are obtained. The solutions for constant deceleration parameter have been investigated in detail for both power – law and exponential forms, also ? =1/3 (Disordered radiation) case has been discussed. The physical and geometrical features of the model are also studied.
