Query: An axisymmetric, hydrodynamical model for the torus wind in AGN   We report on time-dependent axisymmetric simulations of an X-ray excited flow
from a parsec-scale, rotating, cold torus around an active galactic nucleus.
Our simulations account for radiative heating and cooling and radiation
pressure force. The simulations follow the development of a broad bi-conical
outflow induced mainly by X-ray heating. We compute synthetic spectra predicted
by our simulations. The wind characteristics and the spectra support the
hypothesis that a rotationally supported torus can serve as the source of a
wind which is responsible for the warm absorber gas observed in the X-ray
spectra of many Seyfert galaxies.
