Abstract: A three phase free piston type double acting Stirling engine model is proposed and validated using experimental results. The modeling strategy is based on a combination of two sub-models: a global thermal model of the engine to deal with heat sources coupling and a detailed equivalent electrical network model which accounts for the gas and mechanical dynamic physics of the engine. Derived features, such as the amplitude, the frequency, the compression and the expansion powers are then finally obtained. The model is experimentally validated with a prototype of a free piston Stirling engine. Mean error on the amplitude, the frequency, the internal temperatures and the compression and expansion powers is 9%, so the model is considered accurate enough to predict performances.
