Factors Influencing the Thermodynamic Efficiency of Stirling Engines

Abstract: This meta-study examines the factors which contribute to Stirling engine efficiency. Working fluids should have high specific heat capacity, low viscosity and low density making noble gases the most suitable. Each different working fluid has its own optimum power output at varying pressures and temperatures. The best being Helium at 4.14 MPa and 922K. Dead volume also affects the power output of Stirling engines. Theoretical engines with zero dead volume are ideal but dead volume can occupy over 50% of the eng… Show more

“…The energetic and efficiency of Stirling engines characterization of the ideal Stirling engine cycle is based on the first and second principle of thermodynamics that establishes the connection between the mechanical work performed, the amount of heat and the variation of the internal energy of the working gas [Allan J. Organ, 2010;G. Giannakakis et al, 2017;G.…”

“…Any appropriate driving mechanism moves the gas inside the enclosed space that separates the chamber's heated and cooled sections. [2]. The Stirling engine may be built in one of three distinct designs are alpha, beta, and gamma (figure 1), each type has the similar components and principal work with different mechanical arrangement design.…”
