文摘

Thermal performances of two-phase thermosyphon loop in rotating thin pad at 0–500 rev/min are examined with Nu and Rth correlations devised. Bo elevation at rotation less than 1 g extends coverage of vapor blanket to impede boiling heat transfer. Rotation above 10 g transits intermittent/periodic interfacial structures into bubble streams, leading to beneficial Bo effects. Increases of Rth,con activate smaller nucleate sites to elevate Nueva but reduce sub-cooling temperatures to suppress Nucon. Enhanced phase segregations by raising Ω improve Rth performances and boiling/condensation heat transfers.
