Abstract

A vertical wind tunnel which will support droplets in the size range of 50–200 μ is described. It consists of three sections, a diffuser, a profile forming section, and the observational section. The construction details of all three sections are provided with emphasis on velocity profile formation. Its materials are such that experiments requiring a clean atmosphere can be performed on droplets less than 200 μ in diameter.
