EPG design session v5: best candidate (η=60.5%, 176.4W)

Sweep — Break the I²R wall with heavier AWG at fixed turns, push velocity past laminar to test EMF-vs-hydraulic scaling, and drive coil/pitch modulation below 0.10 to find diminishing-ripple onset.

Score 0.971 — η 60.5%, 176.44 W net

Pathway — bore 80.0mm, loop 1000mm, spiral pitch 90mm
Coil array — 5 × 2400 turns AWG16, 6mm long (3167m wire, 41.71Ω)
Medium — slurry, φ=25.0%, remanence 65% → M 61.8 kA/m, B 596 G
Flow — 1.00 m/s (3.3 fps), Re 1824 laminar, ΔP 425 Pa
Modulation — depth 0.993 — coil/pitch 0.07
Output — 176.10 V into 66.0Ω at 11.1 Hz (matched load would be 41.71Ω)
