Abstract: A novel zero dimensional finite-time thermodynamic, three zones (compression, expansion and regenerator volumes) model of a generic Stirling engine has been developed. Time-dependant heat transfers and losses are considered in the three zones and with the surrounding. The model calculates the evolution of gas temperature, mass and pressure in each zone. Parametric studies and optimization of the engine are facilitated due to easy change of multiple engine parameters. Experimental validation of the model and calibration of transfer coefficients are carried out over a large range of temperature and rotation speed through comparison with a scaled instrumented engine for different geometrical configurations.
