The condensation of R11 vapor on vertical fluted tubes in three modes (heave, sway and roll) of sinusoidal vibration were studied experimentally in order to evalute the effect of motion on the heat transfer performance for a moving ocean platform such as the OTEC plant. The cross-sectional shapes of the groove of the used tubes were the circular arc and triangle respectively. The effects of heave and sway motion on heat transfer performance were not detected at a vibrating force of up to 0.135g. But the roll motion enhanced the heat transfer performance as the amplitude or frequency became larger. This effect was recognized when the vibrating force became 0.11g on larger.
