Bianchi Type-I Universe with Wet Dark Fluid in Scalar-Tensor Theory of Gravitation

Abstract

Field equations in the presence of wet dark fluid space-time. A new equation of state for the dark energy component of the Universe has been used. It is modeled on the equation of state ) ( *     p which can describe a liquid for example water. The exact solutions are obtained in quadrature form. The solution for both power-law and exponential forms are studied. The physical and geometrical properties of the model are also studied.
