temperature difference actually achieved to the maximum temperature difference ther-
modynamically available.
Several evaporator options have been proposed and analyzed for OC-OTEC. They
include open channel ow, falling lms, falling jets, and spout evaporators. These are
shown schematically in Figure 11.9. Based upon extensive experiments at the SERI test
facility [6], the single-spout evaporator was found to be the most suitable conguration.
The effectiveness measured in experiments with and without screens placed above the
pipe outlet varied between 0.9 and 0.97, as shown in Figu ...
