Abstract

Measurements of the deposition of 50, 90 and 150 μm droplets on the wall of a 5.08 cm pipe are presented. The droplets were introduced from an orifice in the center of the pipe at approximately the same velocity as downward flowing air. The deposition rate is described by a diffusion model where the diffusion coefficient of the droplets is constant and the velocity profile is uniform. It is shown that special attention has to be paid to the formulation of the boundary condition at the wall.
