Description

The black hole accretion disks contain highly ionized Fe, including C${}_{IV}$, N${}_V$, and O${}_{VI}$ at a temperature of about ${10}^8$K. The relatively hot accretion disk (${10}^8$K) and the relatively cool surrounding medium (${10}^6$K) are mixed and the iron is ionized and recombined to release the X-ray. This paper investigate the physical properties of turbulent mixing layers and the production of highly ionized irons, by using hydrodynamic simulations with radiative cooling and non-equilibrium ionization (NEI) calculations.
