EPG design session v4: best candidate (η=59.6%, 231.3W)
Sweep: Separate hydraulic cost from induced EMF via velocity sweep, push modulation depth at lower copper via pitch-vs-coil-length, and evaluate at the matched ~40Ω load instead of 100Ω.
Score 0.965 — η 59.6%, 231.34 W net
Pathway bore 80.0mm, loop 1000mm, spiral pitch 60mm Coil array 5 × 2400 turns AWG18, 8mm long (3167m wire, 66.28Ω) Medium slurry, φ=25.0%, remanence 65% → M 61.8 kA/m, B 583 G Flow 1.00 m/s (3.3 fps), Re 1829 laminar, ΔP 424 Pa
Modulation depth 0.971 — coil/pitch 0.13 Output 252.91 V into 100.0Ω at 16.7 Hz (matched load would be 66.28Ω)
