Finite Time Thermodynamic Analysis of Complex Brayton Cycle
In the present chapter, the effects of some important cycle parameters on the thermodynamic performance of complex Brayton cycles are studied by means of analytical relations using the concept of finite time thermodynamics (Curzon and Alhborn 1975). The analysis presented in this paper demonstrates the main parameters governing changes in performance variables and provides simple relations amongst the different cycle parameters. Thus, the use of analytical relations allows an understanding of the effects of different cycle parameters, such as, the turbine outlet temperature, reheat, intercooling, isothermal heat addition, cycle pressure ratios, etc. and provides a means for a quick estimation of such effects in a wide range.
