Bianchi type-II universe with wet dark fluid in general theory of relativity

Abstract

In this paper, dark energy models of the universe filled with wet dark fluid are constructed in the frame work of LRS Bianchi type-II space-time in General Theory of Relativity. A new equation of state modeled on the equation of state $p = \gamma ( \rho - \rho_{*} )$ , which can describe liquid including water, is used. The exact solutions of Einstein’s field equations are obtained in quadrature form and the models corresponding to the cases $\gamma = 0$ and $\gamma = 1$ are discussed in details.
