Improvements to a Smoke Generator for Use in Wind Tunnels

Abstract

In order to overcome disadvantages in existing methods, a new smoke- system for wind tunnels has been investigated. The system consists simply of a device for mixing jets of anhydrous ammonia and sulphur dioxide gases. It is instantly controllable, produces dense white smoke without clogging, is easily portable, and poses no fire risk. Provided simple precuations are taken there is no danger of toxic concentrations building up, and the substances used are non-corrosive, readily available,, and cheap. The system has been improved by the design of a large-capacity probe for use in high-speed airstreams.
