Abstract
Data on the seeding particle distribution in the flow of a supersonic wind tunnel with electric-arc heating of the working gas are presented. The application of statistical approaches based on gray-level co-occurrence matrices (GLCM) to identify textural features corresponding to different boundary-layer flow regimes is discussed.
