A general multi-component method for the description of dust grain processing

D. Krüger, P. Woitke and E. Sedlmayr

Astronomy & Astrophysics Sup., Vol. 113, 593-602 (1995)

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
