Abstract

Recent studies that dealt with supersonic/hypersonic flows over various geometrical configurations, which resemble the shapes of supersonic/hypersonic intakes and vehicles, revealed that there were situations in which spatial and temporal oscillating pressure fields were established in steady flows. It was found that the oscillating pressure fields could reach extremely high-pressure peaks. Pressure peaks that were more than two orders of magnitude (even up to 500 times) larger than the ambient pressure were obtained in some of these studies. It is hypothesized that the oscillating pressure fields with the extremely high pressure peaks could cause sever structural damages to the surfaces of supersonic/hypersonic intakes and vehicles over which they are developed.
