Abstract

The desire to increase the thermodynamic efficiency of power machines and units now leads to use of gas turbine units with heat recovery in the cycle. Such devices are used as power and transport GTUs, as well as energy conversion units for prospective fourth generation nuclear power plants. Thermodynamic efficiency of the ideal Brighton cycle with heat regeneration with constant thermophysical properties of the working fluid, as well as the Brighton cycle with heat recovery and the wetting of the working fluid at the inlet to the turbine (with variable thermophysical properties of the working fluid) is considered in this paper. The inapplicability of comparison of the thermal efficiency of the Brighton cycle with heat recovery and the wetting of the working fluid at the inlet to the turbine with the thermal efficiency of the equivalent ideal Carnot cycle is shown.
