FIG. 9:D3 DISK: DROPLET FLOW PATH (TOP VIEW) HUB PCHE (108) A: Spray + Coriolis drift IR F_cent = w^2 r F_cor (tangential) Rotation (2 RPM) R = 10 m 104 106 110 B: Rim Capture C: Fluid return via spoke D3 DISK FLUID CYCLE (TOP VIEW): A. Hub nozzles (110) spray CB-DC705 droplets radially outward:centrifugal force drives outward drift, Coriolis causes tangential deviation B. Cooled droplets captured by dual-layer Ti mesh at rim collector (104):>99.99% capture efficiency per cycle C. Collected fluid drains through rim manifold, returns to hub PCHE (108) via spoke channels (106):6 CFRP spokes with integrated fluid lines
