Finite physical dimensions thermodynamic analysis for gamma Stirling engine

In the foreseeable future, the depletion of finite fossil fuel reserves is a growing concern due to the increasing consumption of these resources by humans. Moreover, the emission of greenhouse gases from fossil fuel consumption contributes to global warming, resulting in significant harm to the Earth's ecosystem. The Stirling engine (SE) offers an outstanding solution for harnessing various heat sources, including solar, nuclear, and fossil fuels, among others. It provides numerous advantages, such as high efficiency, a long lifespan, low noise levels, and minimal or no emissions. This paper conducts a finite physical dimensions thermodynamic analysis (FPDT) on a gamma-type double piston cylinder engine and compares the results with other isothermal models and experimental data. The current model's results align closely with other thermodynamic models
