A Stirling engine with nominal output power of 1 kW is tested using air and helium as working gases. The influence of working pressure, engine speed and temperature of the hot source is studied, analyzing instantaneous gas pressure as well as instantaneous and stationary temperature at...

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...
