Harmonic Mean Isentropic Exponent Based Thermodynamic Modeling And Optimization Of A Closed Cycle Reheat Gas Turbine Power Plant Cycle

Investigation of closed cycle gas turbine power plant with reheater is performed on the basis of harmonic mean isentropic exponent. Expression for the pressure ratio corresponding to maximum power and maximum dimensionless net work output is derived analytically and it is found that the pressure ratio corresponding to maximum power and the maximum non dimensional net work is high when the ratio of extreme temperatures of cycle (i.e. Tmax and Tmin) and isentropic efficiencies of compressor and turbine (i.e. c and t) are.
