Abstract


A Brayton cycle with internal irreversibilities due to isentropic efficiencies of the turbine and compressor, is analyzed using two criterions. One was developed by the authors~[1] to obtain the maximum efficiency with respect to the isentropic temperature ratio. Another was obtained in~[2] and gives the conditions to obtain a better cycle if a heat exchanger for regeneration is coupled. If the operation regime of the cycle is maximum work or efficiency, then, a regenerator can always be coupled. The conditions of regeneration for other operation regimes are also shown. The numerical optimization of a regenerative cycle is performed.
