Experimental determination of droplet impaction on canopy components of balsam fir.

Abstract

The capture efficiencies of balsam fir canopy components for monodisperse glycerin droplets were measured in a low-speed wind tunnel. Droplets were produced at sizes and wind speeds typical of cloudy conditions in a windy, subalpine environment. Capture efficiencies were evaluated on the basis of the Stokes number.- from Authors
