This paper carries out experimental and numerical investigation of a convergent-divergent nozzle. It is shown that the serpentine shape produces a coupling effect with the flow separation in the overexpanded state. The jet produces thrust deflection at low nozzle pressure ratios and its separation is three-dimensional.
