Numerical Simulation of Hot Accretion Flow around Bondi Radius

Abstract Previous numerical simulations have shown that strong winds can be produced in the hot accretion flows around black holes. Most of those studies focus only on region close to central hole; therefore it is unclear whether wind production stops at large radii Bondi radius. Bu et al. (2016) studied flow radius presence nuclear star gravity. They find that, when stars gravity important–comparable hole gravity, cannot However, for some galaxies, may not strong. In this case, clear. We study with and without thermal conduction by performing hydrodynamical simulations. use virtual particles trajectory method exist based simulation data. Our results show absence radius, which causes mass inflow rate decrease inwards. confirm Yuan (2012), indicate due loss gas via rather than convectional motions.
