Abstract : A massively blowing wedge was studied in a supersonic arc tunnel. The shock wave and separation streamline were visualized in the low density flow by two chemiluminescent techniques. The data obtained under a variety of conditions were found to be correlated by a linear relation between two nondimensional blowing parameters. The two parameters were derived both by dimensional analysis and by an approximate momentum balance analysis. The relation between the blowing parameters found for the wedge also seems to hold for a blowing cone when the three-dimensional geometry is taken into account. (Author)
