A flow visualization system was developed for the Sandia Corporation 12 x 12-inch transonic blowdown wind tunnel. -The arrangement comprises a multiple- source schlieren system with sharp focusing properties to keep the perforated plexiglas side walls out of focus. The detailed mechanical design of the schlieren system is not completed. However, a bench-type setup representative of the final system has been made at the wind tunnel. The system is shown and each component is discussed briefly. (auth).

The use of a multiple-source schlieren system was studied for application to wind tunnels employing perforated walls. Visibility equations are derived showing the influence of geometrical parameters on the schlieren photograph background patterin for first one and then two tunnel walls. A uniformly illuminated background pattern is shown to be easily attained with a single perforated wall, but not with two identically perforated walls. A method of obtaining a uniformly illuminated background pattern for the two wall case by relocating the holes in one perforated tunnel wall is discussed. The use of an external source plate is shown to increase system sensitivity at no sacrifice in background pattern. The multiple-source schlieren system is also shown to be useful with transparent walls where the conventional system is unsatisfactory.
