Applications of dark central ground interferometry
Abstract
The application of dark central ground interferometry in a supersonic wind tunnel is presented. Examples of this method as a quantitative flow visualization technique for several types of supersonic flowfields are presented. Theoretical work is presented regarding the effects of vibrations and filter size. The method is shown to be an inexpensive, easy to use tool for situations requiring interferograms for flow visualization.
