WFC design session v12: best candidate (Q=91.2, 96.1kHz)
Sweep — Choke turns/gauge unavailable as direct params, so instead push into water/electrode chemistry space (ppm, temp, surface_factor) at fixed adopted geometry to find non-geometric Q/current headroom beyond the exhausted cell-count sweeps
- Cell — 21.8mm rod in 26.8mm tube × 60mm, 1 cell(s) parallel → C_eff = 1.39nF, bulk water R = 119166Ω.
- Water/electrodes (Randles) — 0.1ppm Na+ @ 5°C, surface ×0.5 → λ_D 228nm, C_dl 3.8µF, cell series R 12.0Ω, displacement current 99.0%, breakdown margin ×152.
- Chokes — 2 × 0.00099H (129 turns, AWG 18, 15m wire, AC R 0.6Ω each).
- At resonance f_r = 96.06kHz — Xl = 1195Ω, Xc = 1195Ω, tank Q = 91.2, coil Q = 1069.1.
- Cell voltage 1094V from 12V drive (×91.2), series current 915.8mA.
- All constraints satisfied (current <1A, band, wire length).
- Score 0.809.
