摘要: We model, for the first time, Bondi-Hoyle accretion of a fluid with velocity gradients onto Kerr black hole, by numerically solving fully relativistic hydrodynamics equations. Specifically, we consider supersonic ideal gas, which has perpendicular to relative motion. measure mass and specific angular rates illustrate whether presents unstable patterns or not. The initial parameters, in this work, are gradient $\epsilon_{v}$, hole spin $a$, asymptotic Mach number ${\cal M}_{\infty}$ adiabatic index $\Gamma$. show that flow reaches fairly stationary regime, unlike Newtonian case, where significant fluctuations momentum found. On other hand, special case both density taken into account. number, $a=0.98$ M}_{\infty}=1$, respectively. A kind flip-flop behavior is found at early times; nevertheless, system also steady state.
