| Abstract: | The performance test of a shell-and-plate type evaporator (total surface area 21.95 m2, length 1450 mm, width 235 mm, 100 plates) for ocean thermal energy conversion (OTEC) plants is reported. Freon 22 (R22) and ammonia (NH3) were used as the working fluid. Empirical correlations are proposed for predicting the boiling heat transfer and the heat transfer coefficients on the water side. The water-side pressure drop is about 2.9 × 104 N/m2 when the warm water velocity is 0.7 m/s. The water-side friction factor is obtained. |
