Moving shock wave behaviour in area contractions of arbitrary shape
Abstract
Complex reflections and interactions resulting from shock wave motion in contractions of arbitrary shape are examined theoretically and experimentally. The locus of the discontinuities occurring in the shock front has been determined using an incremental procedure based on three-shock theory, ray-shock theory and established experimental results for simple, plane wall corners. A characteristics method based on ray-shock theory is used to describe the shock behavior elsewhere. Experiments with a parabolic and a radiused ramp contraction confirm the predicted wave shapes. The actual discontinuity locus falls very close to that predicted using the established experimental data while ray-shock and three-shock theory show some positional difference.-
