This work focuses on the analysis of simple and recuperative organic Rankine cycles, for four fluids that can operate at temperatures ∼ 450 °C without suffering thermal degradation, as well as a reheated steam Rankine cycle and a supercritical CO2 Brayton cycle (Fig. 4). Show abstract ...
The Rankine cycle is one which can operate with these parameters. Isothermal expansion due to evaporation of water can be almost 100% efficient, as can isothermal compression due to condensation of steam. Only a very small portion of the work extracted by the adiabatic expansion of steam in the...
Find also the efficiency of the combined cyde using constant specific heats for air at room temperature If an ideal regenerator is added to the gas cycde portion of the combined cycle, how much does this change the efficiency of the combined cycle?...

Based on the graphical analysis method in temperature-entropy diagram, the limiting performances, which could be measured using limiting thermal efficiency and limiting thermodynamics perfection, of 4 typical zeotropic working fluids used in simple and regenerative organic Rankine cycle were proposed and ...
The molten salt could then be stored, and when desired, electricity could be generated by pumping the hot salt to a different system of heat exchangers that transfer the thermal energy from the hot salt to water in order to produce steam to drive a conventional Rankine cycle turbine generator...
