Modeling, Simulation, and Reconstruction of 2-Reservoir Heat-to-Power Processes in Finite-Time Thermodynamics.

Area of Science:

• Thermodynamics
• Physical Sciences

Background:

• Finite-Time Thermodynamics (FTT) models ideal endoreversible processes.
• Real-world systems exhibit irreversibilities not fully captured by basic FTT models.

Purpose of the Study:

• To investigate the connection between endoreversible FTT models and actual irreversible processes.
• To introduce complementary concepts of Simulation and Reconstruction for analyzing these systems.
• To incorporate internal irreversibilities into FTT descriptions.

Main Methods:

• Introduction of Simulation and Reconstruction concepts.
• Utilization of machine diagrams for Simulation.
• Employment of (reconstruction) parameter diagrams for Reconstruction.
• Incorporation of contact quantities, such as contact temperature, to model internal irreversibilities.

Main Results:

• Demonstrated the utility of Simulation and Reconstruction for linking theoretical models to real processes.
• Emphasized the importance of specific machine and parameter diagrams.
• Successfully integrated the treatment of internal irreversibilities into FTT.

Conclusions:

• Simulation and Reconstruction provide a robust framework for analyzing irreversible thermal processes within FTT.
• Contact temperature is a key parameter for accurately describing internal irreversibilities.
• This approach enhances the applicability of FTT to real-world thermodynamic systems.
