  • Fundamental Characteristics of Power Output on Ocean Thermal Energy Conversion System Using Cross-flow Heat Exchangers

抄録

<p>Ocean thermal energy conversion (OTEC) is a system, which uses the seawater temperature difference between the surface and the deep to generate electricity. The balance of performance of components will determine the net power output from OTEC. Previously, the finite-time thermodynamics (FTT) models has been constructed for calculating the maximum net power of OTEC heat engines. This research evaluates the power output characteristic of 15kW OTEC system using cross-flow plate heat exchangers by comparing the exceptional data with the theoretical maximum power output based on FTT. In the experiment, the Rankine cycle using pure ammonia as a working fluid was used. As the results, the analysis of the experimental results show the power generation characteristic and the overall internal irreversibility of heat engine.</p>
