Modelling of a low temperature differential Stirling Engine.

Abstract: A full theoretical model of a low temperature difference Stirling engine is developed in this paper.The model, which starts from the first principles, gives a full differential description of the major componentsof the engine: the behaviour of the gas in the expansion and the compression spaces; the behaviour of thegas in the regenerator; the dynamic behaviour of the displacer and the power piston/flywheel assembly. Asmall fully instrumented the engine is used to validate the model. The theoretical model is in goodagreement with the experimental data and describes well all features exhibited by the engine
