Power Optimization of a Constant-Temperature Heat Reservoir Irreversible Simple Gas Turbine Cycle for Space Power Plant
A simple gas turbine cycle for space power plant includes three parts:the first is a reactor,the second is closed gas turbine cycle with a compressor,a turbine and two heat exchangers,and the third is a radiator panel to dissipate heat to cosmic space.In this paper,an irreversible simple closed gas turbine cycle model for space power plant is established,and thermal efficiency and power output of the cycle are derived.When total heat transfer area of radiator panel and two heat exchangers is fixed,the maximum power output of the plant is obtained by optimizing area distributions among two HEXs and radiator panel,and the double maximum power output is obtained by optimizing temperature of the low temperature heat sink.
