Abstract
The paper presents an analysis of a Stirling engine regenerator. Due to the high dependence of Stirling engine performance and efficiency on the efficiency of the regenerator, it is imperative, when modeling the engine, to create a regenerator model that is both accurate and which allows for a high computational speed. In this work, the authors propose a one-dimensional, real gas model to work in conjunction with a real gas zero-dimensional differential model of an alpha Stirling engine (which has been discussed in previously published work). This model is compared with simple NTU analysis and CFD modeling.
