✦ Synopsis


AbstractÐSpeci®c 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 ¯uid 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 speci®c 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 bene®cial applications in industry.

The specific output power of a shipboard nuclear propulsion system is analyzed. The plant consists of a Rankine cycle coupled to coolant from a nuclear reactor (heat source) and ocean water (heat sink) by heat transfer. The specific power is optimized by using thermodynamic software called CyclePad
