Abstract: The blue-shifted broad emission lines and/or broad absorption lines seen in many luminous quasars are striking evidence for a broad line region in which radiation driving plays an important role. We consider the case for a similar role for radiation driving beyond the dust sublimation radius by focussing on the infrared regime where the relationship between luminosity and the prominence of the 3–5μm bump may be key. To investigate this further, we apply the 3D hydrodynamic wind model of Everett (2005) to predict the infrared spectral energy distributions of quasars. The presence of the 3–5μm bump and strong, broad silicate features can be reproduced with this dynamical wind model when radiation driving on dust is taken into account.
