Abstract:
In this paper, we have constructed the cosmological model of the universe in a two-fluid environment
with a newly developed mathematical formalism. In order
to construct the model, Binachi type V (BV) space time is
considered with a time varying deceleration parameter. Both
the fluids, the viscous fluid and the dark energy (DE) fluid
have shown their dominance respectively in early time and
late time of the cosmic evolution. The scale factor that simulates the cosmic transition based on the value of the bulk
viscous coefficient. Within the developed formalism, a general form of the skewness parameters is also obtained as a
functional form of the scale factor. The physical parameter
of the model such as equation of state (EoS) parameter is
also derived and analysed. The state finder diagnostic pair
is also obtained to understand the geometrical nature of the
model.
