  We model the active polar fluid as a collection of orientable objects
supplied with active stresses and momentum damping coming from the viscosity of
bulk fluid medium. The growth kinetics of local orientation field is studied.
The effect of active fluid is contractile or extensile depending upon the sign
of the active stress. We explore the growth kinetics for different activities.
We observe that for both extensile and contractile cases the growth is altered
by a prefactor when compared to the equilibrium Model A. We find that the
extensile fluid enhances the domain growth whereas the contractile fluid
supresses it. The asymptotic growth becomes pure algebraic for large magnitudes
of activity. We also find that the domain morphology remains unchanged due to
activity and system shows the good dynamic scaling for all activities. Our
study provides the understanding of ordering kinetics in active polar gel.
