Abstract:

The results of an experimental investigation of unsteady supersonic flow past cylinders are presented. The purpose of the experiment was to determine the basic criteria characterizing an unsteady flow behind a two-dimensional shock wave having constant time parameters and to ascertain the correlation between the variable location of a reflected shock wave and the surface pressure on the body. The experiments were carried out by subjecting cylinders with flat and spherical bluntness to axisymmetrical and transverse flows in a shock tube. The range of the Mach numbers of the incident shock-waves was from 1.5 to 6. The magnitudes of maximum shock detachment distance at the stagnation point obtained were compared with available data and were found to be in good agreement. Author
