2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/3284I review the main results from recent 2-D, time-dependent hydrodynamic models of radiation-driven winds from accretion disks in AGN. I also discuss the physical conditions needed for a disk wind to be shielded from the strong X-rays and to be accelerated to hypersonic velocities. I conclude with a few remarks on winds in hot stars, low mass young stellar objects, cataclysmic variables, low mass X-ray binaries, and galactic black holes and future work.LaTeX, 6 pages, to be published in "Mass Outflow in Active Galactic Nuclei: New Perspectives" eds.
