Layer A thrust · Layer B = picture

Honesty note. The flow picture is a planar 2D panel solve of the duct section, not an axisymmetric one. Planar flow over-predicts how far the duct's influence reaches and under-predicts the lip suction peak of the real ring. It drives the picture and relative trends only (which lip separates first, where the stagnation point sits, crossflow asymmetry). Thrust and power come from Layer A. The C_p map is scaled so its lip force matches Layer A's duct thrust at axial static. The 3D field is the 2D solve swept round the axis.
