Bianchi Type I (Kasner form) with wet dark fluid in f(R, T) gravity

Abstract

In this paper, Bianchi type I space time in Kasner form with wet dark  fluid (WDF), which is a candidate for dark energy (DE), in the framework of f(R, T) gravity, R and T denote the Ricci scalar and the trace of the energy–momentum tensor, respectively (Harko et al. Phys. Rev. D, 84, 024020 (2011)) has been investigated. Equation of state in the form of WDF for the DE component of the universe is considered.It is modeled on the equation of state  . The exact solutions to the corresponding field equations are obtained for power-law and exponential volumetric expansion. The geometrical and physical parameters for both the models are studied.
