  In recent past, the progresses in accretion studies onto relativistically
gravitating central objects like a Schwarzschild singularity reveal that the
accretion flow must be transonic. For such cases, the radial inward speed
gradient can be written as a numerator by denominator form among which the
later vanishes somewhere in between infinite distance from the attracter to the
event horizon of the same. For sustainability of a physical solutions, the
numerator should vanish at the same radial distance where denominator does
vanish. From this point, we obtain a second degree first order differential
equation of radial inward speed and hence we obtain two branches of flow,
namely accretion and wind. For adiabatic accretion case, the wind curve is
formed to be more or less parallel to the radial distance axis as we move far
from the central object. For dark energy accretion, this curve is parallel to
the radial velocity axis. Here we face a question. Why there is no fluid speed
profiles in between these two extremities. While searching the reasons, we
follow that dark energy, if treated as an accreting object, should stay around
the central \emph{compact star} and hence will contaminate the metric which
propertises the compact star. In this research work, we have proposed a model
with a rotating black hole embedded in quintessence where quintessence equation
of state and spin parameters of the black hole are regulatory factors of the
model. The resulting accretion and wind curves are studied. The Effect of
negative pressure of dark energy is found to get catalyzed by the entry of the
spin of the black hole. We tally our results with observations of accretion or
outflow phenomenon near to different quasars.
