Since the beginning of Thermodynamics in the middle of the 19.century its main motivation was the description of steam engines and the liquid to gas transition of water.

Although there could be other ways to produce these structures, such as interactions with clumps of dense gas or precession of the central engine, these in turn can also give rise to the growth of the instabilities via coupling to any of the unstable modes (see, e.g.
Anatomy of helical relativistic jets: The case of S5 0836+710
The gas temperature and ionization state in the wind are calculated self-consistently from the photoionization and heating rate of the central engine.
Dynamics of line-driven disk winds in Active Galactic Nuclei
Their model relies on the local disk radiation to launch gas from the disk and on the central radiation to accelerate the gas in the radial direction to high velocities. A key ingredient to this model is that the central engine radiation is attenuated by ’hitchhiking’ gas located between the central engine and wind.
Dynamics of line-driven disk winds in Active Galactic Nuclei
Once the gas is high enough above the disk, the radiation force due to the central engine accelerates the gas to high velocity.
Dynamics of line-driven disk winds in Active Galactic Nuclei
X-ray source and wind, namely for NH >∼ 1024 cm−2 (τX >> 1) the gas is well shielded from the X-rays but at the same time it is also shielded from any other radiation from the central engine including the UV radiation.
Dynamics of line-driven disk winds in Active Galactic Nuclei
In this case, the line force from the central engine could be so much reduced that it may not accelerate the gas to high radial velocities and no strong wind will be produced.
