# Bianchi type-II universe with wet dark fluid in General Theory of Relativity

## TL;DR

This paper develops dark energy models in a Bianchi type-II universe filled with wet dark fluid, deriving exact solutions to Einstein's equations and exploring specific cases of the fluid's equation of state.

## Contribution

It introduces a new wet dark fluid equation of state into Bianchi type-II models and provides exact solutions within General Relativity.

## Key findings

- Exact solutions for the Einstein field equations are obtained.
- Models for specific cases of the equation of state are discussed.
- The behavior of the universe with wet dark fluid is analyzed.

## Abstract

In this paper, dark energy models of the universe filled with wet dark fluid are constructed in the framework 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 a 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 detail.
