Cosmic expansion of Bianchi type-III wet dark fluid model in theory of gravity

In this study, our primary focus was the examination of the Bianchi type-III metric in the context of f(R) gravitational theory incorporating a wet dark fluid. We have determined that the metric solution corresponds to an expanding universe, achieved by assuming a negative constant deceleration parameter and engaging a power-law relationship. Furthermore, we have conducted a visual assessment of the metric's dynamic and geometric characteristics using graphical representations.
