Massive blowing experiments.

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 derived by an approximate momentum balance analysis. Viscous interaction effects were found to be important in determining pressure levels and shock-wave angles at a Reynolds number of ^178. 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.
