Summary
The two-dimensional wake in a supersonic flow at high Reynolds number is investigated. Mean and fluctuating velocities measurements are discussed following the similarity criterions, and comparisons with incompressible wake behaviour are done. We test the compressibility effects in such a flow. Space and space-time correlations are performed for two downstream stations. Comparisons with the double-roller eddy model established for incompressible wake of cylinder are performed; the classical model doesn’t apply to the wake under study. Isocorrelation curves are plotted and show inclined shapes whose angles of incidence are related to the downstream location. Filtered correlations show the evolution of the life-duration and the phase velocities following the size of the structures.
