Abstract

Specific power, power per unit total heat exchanger surface area, of a heat engine is chosen to be the objective function in the design of an OTEC (Ocean Thermal Energy Conversion) Rankine power plant. An ICAI (Intelligent Computer Aided Instruction) computer software, CyclePad, with Refrigerant-12 as the working fluid operating between a warm ocean water heat source and a cold ocean water heat sink is used in the design process. Through manipulation of the boiler pressure and condenser pressure, the specific power of the OTEC plant is calculated and an upper bound is determined. This bound can direct the design of current and future OTEC heat engines to provide beneficial applications in industry.
