Computer Modeling of a Novel Mechanical Arrangement of a Free-Piston Stirling Engine

S. Ghozzi and R. Boukhanouf
Abstract—The principle of a new design of Free Piston Stirling Engine (FPSE) prototype for small-scale power generator, such as solar dish Stirling engine, has been described in this paper. The design uses a special bellows with high reliability and long life mechanical springs displacer and power piston. A mathematical model has been developed to analyze the thermal and dynamic performance of the engine as well as to evaluate the output power and thermal efficiency of the cycle. Two methods of Stirling cycle analysis, which are Ideal Adiabatic and Simple Analysis, were carried out in order to calculate the performance and efficiency of the conserved FPSE design. A computer program is in progress so that the thermal cycle of Stirling simulated. The results extracted from the simulation proved a valuable thermal efficiency and overall satisfactory performance for the new FPSE design.

Index Terms—Stirling engine, free piston, power generation, low temperature, small-scale system.
