Résumé

In present numerical research, the mathematical model to accurately simulate the performance and detailed behavior of Stirling refrigerator was investigated. The mathematical model is for an alpha Stirling refrigerator with helium as the working fluid and will be useful in optimizing the mechanical design of these machines. A complete non-linear mathematical model of the machine, including helium thermodynamics, and heat transfer from the walls, as well as heat transfer and gas resistance in the regenerator, is developed. Non-dimensional groups are derived, and the mathematical model is numerically solved. Important design parameters are varied and their effect on refrigerator performance determined. The simulation results of a Stirling refrigerator are presented and these include heat transfer and coefficient of performance.
