Net Performance

Axial thrust 0 (cancels)
Mixing violence Very high
Tesla rectification Passive ✓
Flow at throat Purely axial
Primary function: confined hot/cold mixing. Flow arrives mostly swirling (15°) at the rim, transitions to mostly axial (74°) at the toroid throat. Hot and cold meet with |Δv|=135 — tangential and axial components fully opposed. Tesla-valve geometry passively resists backflow.

To convert to thrust: reduce exit elevation from 77° to ~30° so hot/cold exits share a z-direction.
