Abstract:
We derive a special differential form of a balance or conservation equation for the grain size distribution function. This equation describes the evolution of the grain size spectrum in one-dimensional stationary flows also taking into account possible size dependent drift velocities of the grains relative to the

Abstract:
Self-consistent two-fluid models of stationary dust driven winds around cool C-stars have been calculated. The dust and the gas component are coupled by the condensation of dust from the gas phase and grain-gas collisions and are described by separate sets of equations.
