Abstract

A two-dimensional color schlieren method developed by Settles (1970) is one of the best visualized technique of compressible flow field. By using this method, direction of density gradient is indicated by three primary colors (red, blue and green) and three neutral colors (yellow, purple and blue-green). The clear neutral colors are required to survey the direction precisely. The optical setup consists of a flash, a ring-shaped tricolor filter mask, a couple of parabolic mirrors, a pinhole and a still camera. The quality of a developed color image by this method depends on three parameters; diameter of the pinhole D1, diameter of the filter mask D2 and thickness of the color band D3. We clarified suitable values of these parameters. The following results are obtained from this study: (1) D1 influences the visible area and sensitivity, (2) D2 influences developed color image, (3) D3 influences brightness.
