Improved Chambadal Model with New Optimization Results.

Area of Science:

• Thermodynamics
• Heat Engine Optimization
• Irreversible Processes

Background:

• The Chambadal model provides a framework for analyzing irreversible heat engines.
• Previous work focused on entropy production in Carnot cycles.
• A need exists to compare different optimization approaches for enhanced engine performance.

Purpose of the Study:

• To continue the optimization of the irreversible Carnot engine based on the Chambadal model.
• To compare the classical entropy production approach with a novel energy degradation approach.
• To evaluate the physical representativeness of each optimization method.

Main Methods:

• Retrieving and enriching existing data from the Special Issue "Carnot Cycle and Heat Engine Fundamentals and Applications II".
• Applying sequential optimization techniques to both entropy production and energy degradation models.
• Analyzing the impact of each approach on engine performance metrics.

Main Results:

• Both entropy production and energy degradation approaches were applied using sequential optimization.
• The energy degradation approach yielded slightly different results compared to the entropy production method.
• The energy degradation approach highlights energy conservation and defines bounds for mechanical energy and power output.

Conclusions:

• The energy degradation approach is considered more representative of physical principles in engine modeling.
• This method emphasizes energy conservation and establishes upper and lower bounds for engine output.
• Further research can build upon this energy degradation framework for improved irreversible Carnot engine design.
