Construction of simulation model for OTEC plant using Uehara cycle

Ocean Thermal Energy Conversion (OTEC) converts heat energy into electricity using the 20 to 27 °C temperature difference between warm seawater at the surface and cold seawater in the depths. In this paper, a simulation model for an OTEC plant, which uses the Uehara cycle with an ammonia–water mixtu...

Zusammenfassung:Ocean Thermal Energy Conversion (OTEC) converts heat energy into electricity using the 20 to 27 °C temperature difference between warm seawater at the surface and cold seawater in the depths. In this paper, a simulation model for an OTEC plant, which uses the Uehara cycle with an ammonia–water mixture as working fluid, is constructed based on the mass balance and the heat balance. A method of initial value determination for numerical simulation is developed. The accuracy of the simulation model was evaluated by comparison with the experimental results of an OTEC basic experimental equipment. © 2011 Wiley Periodicals, Inc.
