Abstract
A zero dimensional finite-time thermodynamic, three zones model of a generic Stirling engine has been developed and experimentally validated. Taking into account time-dependant heat transfers and losses, the model calculates the evolution of gas temperature, mass and pressure in each zone. The architecture of the model, an assembly of blocks, permits an easy change of engine characteristics, geometries, gas proprieties. It is therefore possible to test rapidly various modifications on the numerical engine to see their impact on the engine performances and so manufacturing only it seems interesting.
