Abstract: The irreversible cycle model of a regenerative modified complex Brayton cycle has been established for the finite heat capacities of external reservoirs. The power output and efficiency have been optimized with respect to the cycle temperatures and the optimum performance parameters are calculated for a typical set of operating condition. It is found that there are optimal values of the intercooling, reheat and cycle pressure ratios at which the cycle attains the maximum performance. The optimal performance parameters are also found to be increasing function of the effectiveness of different heat exchangers, components efficiency and the heat capacitance rates of the external fluids, while it is found to be reversed in the case of the working fluid heat capacitance rate. The optimum operating parameters, the intercooling, reheat and cycle pressure ratios etc corresponding to the different performance parameters are obtained and discussed in detail. The results obtained here are general and some of the important conclusions in the relevant references can be obtained directly from this paper.
