We carry out numerical simulation of accretion flows around a black hole in presence of both viscous and cooling effects. Instead of using a constant α parameter throughout the simulation grid, we assume that α is maximum on the equatorial plane and gradually goes down in the perpendicular direction We show that when the injected sub-Keplerian flow angular momentum is high enough and/or the viscosity and also cooling is high enough, Two Component \bf Accretion Flow (TCAF) would be formed, otherwise the sub-Keplerian flow would remain sub-Keplerian. We see that a Keplerian disk is produced on the equatorial plane. Time variations of the total, Keplerian and Sub-Keplerian matter are studied with respect to various flow parameters.
