Abstract

The present paper discusses the performance of an irreversible regenerative intercooler–reheat gas turbine cycle under wide ranges of design and operating parameters. The study aims to determine the optimum regions of these parameters that satisfy the most requirements of the gas turbine cycle. The operating parameters are the inlet air temperature to the first stage compressor, inlet temperature and pressure of air entering the high pressure turbine and the thermal size (the heat transfer coefficient–area product) of the whole heat exchangers used in the cycle. A mathematical simulation model is developed to calculate the performance parameters of the cycle under different operating conditions. The developed model achieves most of the requirements of the gas turbine cycle (maximum first and second law efficiencies, minimum back work ratio (BWR), maximum ecological coefficient of performance (ECOP), maximum work output, minimum exergy losses, and finally minimum heat added to the cycle). Achieving some or all of these requirements is based on selection of certain small region in the applicable range of operating parameters. The optimum region resulted from the given operating parameters are: 302 K – 315 K for the minimum temperature, 1340 K – 1360 K for the maximum temperature, 1440 kPa – 2830 kPa for the maximum pressure, and finally 20.7 kW/K – 29.6 kW/K for the heat exchangers' thermal size.
