DYNAMIC SIMULATION OF KINEMATIC STIRLING ENGINES : COUPLED AND DECOUPLED ANALYSIS

摘要

A coupled analysis modelling method of Stirling engines is presented. The main feature of this modelling method is the use of a software package combining the capabilities of a pre-/post-prooessor with a differential algebraic equations solver. As a result, modelling is merely a matter of linking appropriate objects from a model library and the outcoming tool is very flexible and powerful. Some simulation results are presented and compared with those obtained from a decoupled analysis. It clearly appears that the main imperfection of the model does not come from the modelling process itself but from our incomplete knowledge of the physics behind the Stirling engine operation.
