Description
We present preliminary streamline calculations for a parcel of gas in radiatively
driven outflows from accretion disks around active galactic nuclei (AGN). This is done by explicitly
calculating the photoionization balance of the wind at each point (r, ϕ, z) along a given streamline
trajectory. The force multiplier, a measure of the distribution of dimensionless line strengths at a
given point in the wind, is also computed at each point, allowing the computation of the total
radiative acceleration due to the spectral energy distribution of the source. Using the radiative
and gravitational acceleration, the velocity and position of the gas parcel can then be found.
Additionally, we implement a self-consistent attenuation model to account for the absorption of
the SED due to the intervening gas, as well as model the shielding effect of the gas between the
AGN coronal radius and the given launch radius of the wind. We find that in addition to the
number density of the gas prior to the launch point, the initial velocity of the outflow and the mass
accretion rate are two of the dominant factors in the viability of the wind, often determining
both the radial and vertical extents reached by the streamline.
