Abstract:  

The aim of this study is to investigate the performance of a gas turbine cycle equipped with a Stirling engine from the thermodynamic point of view. In this system, part of the heat loss from the gas turbine is transmitted to a Stirling engine to generate more power. In the proposed system analysis, the governing equations of the hybrid cycle are modeled in MATLAB software and Schmidt and ideal adiabatic models are used to solve the Stirling engine. In the analysis of the hybrid cycle, the compressor pressure ratio and turbine inlet temperature were considered as two Important and effective parameters. The results show that reducing the compressor pressure ratio and increasing the turbine inlet temperature improves the performance of the Stirling engine. The results indicate that the use of the hybrid gas turbine cycle and the Stirling engine will increase the power of the gas turbine from 268 kW to 468.6 kW based on the Schmidt model and 457.3 kW based on the ideal adiabatic model. Also, the electrical efficiency of the system increases by 18.1% based on the Schmidt model and about 17.1% based on the ideal adiabatic model.
