抄録：

The ocean thermal energy conversion (OTEC) and hot spring thermal conversion (STEC) are expected to be the next generation energy production systems. Both systems use a plate heat exchangers,and ammonia or ammonia/water mixture as a working fluid. Measurements of boiling heat transfer coefficients for ammonia/water mixture were performed on a vertical flat plate, to clarify and characterize the behavior of ammonia/water mixture on the plate evaporator. The result shows that in case of ammonia/water mixture, the local heat transfer coefficients increases with an increase in vapor quality. In addition, heat transfer coefficient of mixture is smaller than that of pure ammonia except for 99% mixture. An empirical correlation that can predict the local heat transfer coefficient for ammonia/water on vertical flat plate within experimental conditions is also proposed.
