Abstract	Through extensive studies of transonic flows around black hole, our earlier work showed that depending on viscosity, matter may or may not form the steady or oscillating centrifugal pressure supported shock waves in the accretion flows. Highly viscous flows produce a Keplerian disk. It was also envisaged that if there is a vertical variation of viscosity, then the flow on the equatorial plane would be Keplerian, but that above and below would remain sub-Keplerian producing shocks and jets/outflows. This so-called two-component advective flow solution was the basis of Chakrabarti-Titarchuk model of spectral properties of black hole candidates. After extensive numerical simulations, we are now in a position to show that this two component flow actually forms and is very stable against shearing instability. We present these latest results and claim this solution to be the most complete to date among all the non-magnetized disk solution.
