| Abstract: | Thermodynamics analyses and investigation have been performed for a kind of complex gas turbine cycle.Analytical formulae of the cycle work,thermal efficiency,entropy generation and exergy efficiency are derived.The relations of the performance objectives versus intercooling pressure ratio and total pressure ratio are discussed by numerical examples,and the intercooling pressure ratio is optimized.The effects of cycle parameters(such as degree of regeneration,cycle temperature ratio,efficiencies of compressors and turbine,terminal temperature of intercooling process and so on) on the performance objectives are analyzed.The results obtained in this paper may provide some guidelines for the parameter selection and optimal design of practical gas turbine plant. |
| Keywords: | gas turbine cycle the first law of thermodynamics the second law of thermodynamics numerical examples |
