  In this paper, we have presented an FLRW universe containing two-fluids
(baryonic and dark energy) with a deceleration parameter (DP) having a
transition from past decelerating to the present accelerating universe. In this
model, dark energy (DE) interacts with dust to produce a new law for the
density. As per our model, our universe is at present in a phantom phase after
passing through a quintessence phase in the past. The physical importance of
the two-fluid scenario is described in various aspects. The model is shown to
satisfy current observational constraints such as recent Planck results.
Various cosmological parameters relating to the history of the universe have
been investigated.
