We present results of numerical simulation of thin accretion disks and winds. We use the Smoothed Particle Hydrodynamics (SPH) technique for this purpose. We show that the simulation agrees very well with the recent theoretical work on the shock formation. The most significant conclusion is that shocks in an inviscid flow are extremely stable. For the first time, our work also removes the ambiguity in terms of the location and stability of shocks in adiabatic flows.

Simulation based parameter space for shock in transonic, sub-Keplerian accretion flow onto non-rotating black holes
Multi-dimensional simulations show that the parameter space for shocks in non-dissipative transonic sub-Keplerian accretion flows is substantially larger than the analytic prediction, with dynamic boundary layers prod...

Outflow Behavior from the Transonic Advective Disks: A Hydrodynamical Simulation Study
In viscous hydro simulations, colder transonic advective disks drive faster, higher kinetic-energy and momentum bipolar outflows than hotter disks, and outflow strength increases with viscosity.

A general relativistic hydrodynamic simulation code for studying advective, sub-Keplerian accretion flow onto black holes
A GRHD finite-volume code is validated against analytic transonic solutions and applied to 2D sub-Keplerian accretion, recovering shocks and frame-dragging effects.
