abstract

A mathematical model is described which permits the performance analysis of advanced Brayton cycles as used in turbine engines for stationary and flight power plant applications. The model permits the performance evaluation of different working fluids, provides for various component combinations, and facilitates exchange of parameters and variables for off-design point performance and tradeoff studies. The concept of entropy production is used for expressing the losses (irreversible effects, efficiencies) occurring in components of turbine engines. The derived equations permit the use of specific heat as a function of temperature in energy, entropy, and mass flow relations and establish a consistent set which facilitates the generalized performance analysis. Examples related to open and closed Brayton cycles are discussed. Two significant relationships are obtained for the evaluation of working fluids.
