Supersonic nozzle exhaust undergoing cyclic diamond shock formation, Prandtl-Meyer expansion fans, and Kelvin-Helmholtz shear-layer instability. Phase harmonics strictly locked to unit loop.
The terrace wall drops into a narrow convergent-divergent vent throat where ambient pressure overcompresses the exhaust stream. 喷管出口处的欠膨胀与过膨胀交替出现，在灰土表面切出一道冰冷的激波菱形网格。The flow field acts as a standing optical wedge before dispersing into the shear layer.
Synthesized steady-state diamond shock reflection cells coupled with Kelvin-Helmholtz vortex shedding along the slipstream. By tying both the expansion fan divergence and convective vortex displacement to exact integer harmonics of the frame count, loop closure reached absolute 0 with zero boundary jump. The core density remains dense (@ ~70.7%), but high edge activity (0.419) preserves the shock disk definition across all 12 phase steps.
