Critical rankine cycle
WebThe general thermal efficiency equation of the simple Rankine cycle, Thermal efficiency, η = W Turbine – W Pump / Q Boiler. Where, W Turbine is the work output. W Pump is work … A transcritical cycle is a closed thermodynamic cycle where the working fluid goes through both subcritical and supercritical states. In particular, for power cycles the working fluid is kept in the liquid region during the compression phase and in vapour and/or supercritical conditions during the expansion phase. The ultrasupercritical steam Rankine cycle represents a widespread transcritical cy…
