Hydrodynamic simulations of oscillating shock waves in a sub-Keplerian accretion flow around black holes

We study the accretion processes on a black hole by a numerical simulation. We use a grid-based finite difference code for this purpose. We scan the parameter space spanned by the specific energy and the angular momentum and compare the time-dependent solutions with those obtained from theoretical c...
