Shock Oscillations in a Supersonic Jet Exhibiting Antisymmetrical Screech

It was shown that the shocks oscillate at the screech frequency, in a symmetrical or antisymmetrical manner, according to the screech mode. The temporal signals of two diametrically opposed near-field microphones were also considered. At a nozzle pressure ratio of 2.54, corresponding to a flapping m...
