In the present study, a comprehensive analysis is carried out on an ideal regenerative Rankine cycle, based on the use of ICT tools for digital transformation in engineering education. The gap addressed in this work relates to the application of technologies to streamline the thermodynamic analysis of complex cycles, which have been rigorously modeled using the Engineering Equation Solver (E.E.S.) software a high-fidelity computational tool widely recognized for its accuracy in solving nonlinear, multivariable thermodynamic systems. The methodological approach adopted involves a detailed evaluation of the isentropic efficiencies of the main cycle components turbines, pump, and heat exchangers enabling a precise determination of the net power output, the rates of thermal energy transfer to and from the heat exchangers, as well as the quantification of the mass flow rates of extracted steam at specific points in the system for regenerative purposes. Additionally, the computational generation of temperature–entropy (T–s) diagrams is integrated, which serve as fundamental tools for the visualization and validation of the thermodynamic processes involved, allowing for the clear identification of each state in the cycle. Based on this graphical representation and the numerical results derived from the model, key thermodynamic properties are determined, such as specific volume at pump suction, entropy at turbine inlet, and enthalpies associated with each energy transformation, in order to quantitatively establish the isentropic efficiency of the devices and their influence on the overall efficiency of the regenerative cycle. This approach enables not only a comprehensive understanding of system behavior but also the identification of improvement opportunities for the energy optimization of advanced thermoelectric cycles.
