抄録

Oscillation modes of a circular shock wave in a supersonic radial flow were studied both experimentally and theoretically. The pressure fluctuation was measured in concentric positions to investigate the modes of the circular shock wave in the case of mean radii of 70 and 77mm, and the A-D converted signals were statistically correlated. A simple model of an oscillating shock wave was proposed. The frequency of the oscillation increased from low to high values with increasing radius. The oscillation mainly consisted of mode 0 superposed by modes of 1, 2 and 4. The mode 1 is considered to be weak. The experimental frequency of each mode agreed well with the theoretical results.
