A METHOD FOR THE MEASUREMENT OF THE FLOW OF AIR BY MEANS OF SERIES OF ELECTRIC SPARKS
Technical Report
·
OSTI ID:4267304
A technique has been developed in which series of -electric sparks of low current are used to render visible the flow of air. Sparks traversing the air at very high frequency render visible successive displacement profiles; their photographic records furnish a large amount of detailed information. The method is applicable to both subsonic and supersonic flow. The technique has been investigated in detail. Its merits and limitations are appraised as compared with other methods. Numerous photographs are presented to illustrate possible applications. Recommendations are made for the further improvement of the method.
