Formation of two component flows by numerical simulations around black holes

Abstract

In this article, the results of our numerical simulations of a transonic flow having various viscosity parameters and cooling processes are discussed. In our simulation, for each of the cases, the sub-Keplerian matter is injected at outer boundary. Advection of matter towards a black hole is allowed. As a result, we got a complete solution in which the meridional part behaves like a thin and cool Keplerian disk. However, the other part which is away from the equatorial plane behaves like a transonic flow with standing and oscillating shocks. Finally, we observed that, our solution is consistent with the Chakrabarti-Titarchuk two-component advective flow configuration as the flow approaches to a black hole.
