EFFECT OF REGENERATION ON THE PERFORMANCE OF CLOSED-CYCLE GAS TURBINE

The thermodynamic performance within a finite time of a closed cycle gas turbine through an irreversible compression and expansion process under constant temperature heat source is investigated. The relationship both of the cycle power output and the heat efficiency with the cycle pressure ratio is derived, obtaining the optimum power versus efficiency characteristics. For a given heat source, it is found that the regeneration has significant effect on the cycle power, a conclusion which is considerably different from classical analysis results. The heat resistance losses of the actuating medium in the heat exchangers between the high and low temperature heat reservoir and regenerator are considered, also the irreversible losses of compression and expansion in compressor and turbine. It seems that the classical thermodynamic analysis has neglected the effect of heat resistance losses.
